Had a large, obtrusive puddle forming in my driveway every time it rained, which would stay there for several days during the winter, and which was also blocking the pathway to my back door. Paul at Allied worked with me over the course of four months figuring out the best way to deal with the problem. The solution was a channel drain that would lead to my existing gutter drainage system. Because of the topography of my existing driveway, I assumed that there would still be a fair amount of puddling even after the drain was installed and that I would just have to live with it. In the days just after the install however, it rained quite a bit, and the drain worked pretty much perfectly. The puddling has been reduced by about 95%, and the water that does collect is shallow enough to handle easily. After the rain stops, the remains evaporate after a few hours. The small lake that I used to have to walk around is gone. The guys who did the install were professional and very courteous and Paul was very knowledgeable and patient in response to my many, many questions and emails leading up to the install. Would definitely recommend Allied for any project, large or small. read more

They responded quickly to my inquiry. They are very knowledgeable in what they do. We had a new french drain installed. Worked was done in a day. Very professional. read more

When we moved in we noticed there was some sort of water remediation system on the South side of our house that was pulling away from the foundation. We talked to a couple of contractors about the issue and Allied Waterproofing seemed most knowledgeable. We were very happy to work with them. They tested the pipe, determined it drained to a dry well in our backyard (that'd we'd previously been unaware of), and determined that the waterproofing set up was just missing a gasket and connection to the foundation. They did the repair work and everything's been dry and tight so we're very pleased with their work! If we have future drainage remediation work needed we will definitely reach out to Allied Waterproofing & Drainage! read more

Had Allied out to get quoted for a project. Had every opportunity to sell me an expensive solution to my drainage issue but instead offered sound advice and saved me thousands. Super knowledgable and honest. Will absolutely be turning to them for all my waterproofing and drainage issues. read more

Prompt and friendly! Paul was a delight and I was able to work from home without issue.

Reliable, dependable, easy to work with and offered the best price. I had a sewer that needed a liner. The estimate process was easy. I had to coordinate the estimate while out of state. Actual work was done as the owner/estimator had described. Inspection passed with flying colors. Never thought I'd say that I'm happy a sewer liner installation. read more

We had water coming up through a basement floor in heavy rains and everyone had a theory as to why. Paul and his team diagnosed the problem thoroughly, did the work promptly, and kept the cost to the minimum amount reasonable. We've been through two heavy rains: no water. I'd absolutely work with this team again. read more

Paul and his team did a great job installing two different French drains in our yard. Erin was so responsive and a great contact point for the company. Vlad and his crew were absolute animals!! They did such a great job and only took a day and a half. They also did a great job of cleaning up after and making the seams in the yard as invisible as possible. They were extremely competitive with other bids we received and actually bested the other bids by a long shot. I would highly recommend Allied to everyone I know. Great company, great employees and very affordable. read more

Paul and his team were a dream to work with. Both Paul and the crew approached my exterior footing drain project methodically and were always available to answer my questions. They even corrected a problem done by previous work. Will plan on reaching out again for our backyard drainage project. They came highly recommended from a neighbor and now I would happily recommend them too! read more

The team at Allied Waterproofing exceeded all my expectations. Paul approached our problem thoughtfully and provided a creative yet economical solution. The men doing the work arrived on time, kept me informed as to what was going on, and left the yard in immaculate condition. Erin kept me informed as to when to expect the job to be done. She promptly responded to my questions. I could not be more pleased. read more

Excellent team at Allied Waterproofing. Erin is a superstar at the front office. She responded to calls and updates. Paul knows his business with repairs and fair estimates. We had to "problem-solve" some issues with our front driveway drains. No "up-sale" or solutions we did not need. The Crew was in and out like they had never been there. Start with Allied for drainage issues! read more

Our basement flooded due to a formerly, incorrectly installed window well drain. Called Allied, who quickly inspected the problem, offered a number of options and gave me an estimate for my choice of options. Work crew showed up as scheduled, were very polite, explained what they were doing, and asked questions as necessary. They were quick and efficient plus re-landscaped and cleaned up yard to better condition than when they started. They demonstrated and tested the system to show me it was working and asked if I had any questions. Invoice matched the estimate...but the work timeliness and quality FAR EXCEEDED MY EXPECTATIONS. Great company, would highly recommend them! read more

Allied Waterproofing & drainage came highly recommended by a friend who knew someone who used their services. They installed a French drain in my basement which seemingly took in water from everywhere. The guys worked hard for four consecutive days and did a fantastic job. They even went the extra mile and rerouted the water expelled from the sump pump directly to the sewer line (the previous homeowner had some makeshift inefficient convention going on). I'm happy to report that my basement is dry and my piece of mind is restored. read more

Allied was prompt in every aspect of the project. My initial request for a bid was answered promptly, Paul made the assessment and bid proposal quickly and the actual work was done on time and in the amount of time expected. Paul answered all questions and even came back to take another look when I had another question. The crew were hard working and left a very clean space each day. Best of all, the end result was a dry basement throughout all of the record setting rain this year. read more

I'm very happy with the work that the crew did in my crawl space. Paul provided the estimate, and broke the estimate up into two potential jobs--one crawl space drainage system with sump pump and interior trenches and one a job that I might do in the future that involves diverting down spout water. I appreciated that Paul conducted a thorough review of the problems in my crawl space and walked around the property to get a full understanding of the issues that were causing standing water in my crawl space. It is a 1958 house which had a lot of standing water in the crawl due to an existing DIY sump pump that was not up to code and leaked. Paul's estimate also included a drawing of the system which helped me get a better sense of the scale of the repairs. The crew did a great job and took 3 days for the extensive work. The crew even fixed an issue that was caused by a totally different worker without me bringing it up--they repaired the screen on the vent to prevent animals from getting into the crawl space. The work area was also left very clean. Thanks for the hard work and for the repairs! read more

In 2016 my basement flooded after back to back winter rain storms. Paul and Allied Waterproofing gave me a competitive bid to put in a perimeter drainage system which allowed water to go around the basement, not through it. The work was quick and efficient and the system worked flawlessly for years. This past winter we again got back to back storms which caused some water to seep into one corner where a water stopping membrane had been cut too short by carpet installers. Paul and his team once again came out swiftly and addressed the issue without fuss. I would highly recommend Allied for any similar projects. read more

Allied has done two projects for us to waterproof our basement -- one large job involving 1-1/2 sides of our house, and one small job involving a spot leak where water collects on the other side of the house. All aspects of the work they do is simply phenomenal. They diagnose the problem, develop a solution (sometimes more than one to choose from), provide a reasonable bid, and carry out the work. At each step of the process you know you are dealing with total professionals. The crew that came out were knowledgeable, professional, and extraordinarily efficient. For any kind of work we have had on our home, I have never seen a crew work so hard and do the work so well. Everything was done just right. I wish I could give six stars. Recommended X 100! read more

Agree with previous clients - never been so happy to part with my money. From the start, Paul was incredibly responsive, their office team was timely and communicative about scheduling...and when their team showed up on site, they had on masks and clearly had a defined covid protocol to keep themselves and their clients safe. The team quickly completed the work, explained in laymen's terms what was going on and cleaned up meticulously. I'd highly recommend Allied and will be calling them again when we work on the south side of our house. Couldn't be happier with the entire experience. read more

Both Paul and the staff were responsive, thorough, and clearly communicated every aspect of the job from start to finish. Great people to work with. Also, they all closely followed good COVID protocols. I highly recommend them . read more

I live in an old 1919 Craftsman that has been plagued with water issues since I bought it in 2003. I had a sump pump installed 3 years ago, but alas, the immense amount of rain we had at the end of Dec. '19 was too much, and the hydrostatic pressure was such that the water just pressed through the foundation. Allied was the first company to answer my email (within a day), and Paul was able to work around my inconsistent schedule and got a site visit scheduled within a week, which was quite impressive considering the amount of flooding in the region. Paul was prompt, courteous, and matter-of-fact with his assessment and estimate, and immediately recommended doing less than what I had originally envisioned in order to save me some money. I opted to go with the full interior French Drain as well as a gutter redo anyways, and my estimate was well below what I had thought it was going to be. Truth be told, they had to push their start date back due to aforementioned regional flooding and my work schedule, but that was not their fault at all. Once a new start date was settled on, his workers arrived early, had great communication, and were, in a word, AMAZING. They finished ahead of schedule. Clean-up and worksite cleanliness was impeccable. They went above and beyond and even corrected some mistakes with my sump pump that the previous installer had made, replaced the turf they cut and dug up to tie my gutter lines together, and left the entire area spotless. I only wish that I had known they were going to finish early so I could have been home to give the crew a tip in person, they were simply amazing. If I ever have any water issues again (unlikely), I would not hesitate to use Allied again. They are fantastic. read more

I have worked with Paul on a number of projects, but initially he redid our sewer system. His was the best price, value, and quality of work hands down. I can't recommend them highly enough. read more

Can we give them six stars?  Allied Waterproofing and Drainage is tremendous.  We had two vendors give us estimates on resolving a gutter drainage situation.  The first vendor proposed a solution that would have torn up our entire basement and cost about $17,000.  Allied came out and the gentleman immediately grasped that the solution to the situation only required re-directing some gutter drainage.  He showed us how he could easily re-route the water to a safe place in one of our gardens with a minimum of digging and disruption.  His proposal was under $3,000. We hired them.  When their crew showed up, they figured out an ever better way to route the water than we had considered, so as to hide the pipes.  Once done, they then put everything back the way it had been, even re-installing dirt we had dug out of a flower bed.  By the time they were finished, I couldn't tell where they had dug, as they were able to put the topping gravel back so it looked like nothing had ever happened.  I still can't figure out how they did it.  The whole job was done in one day and their clean-up was superb.  I would hire them again without hesitation. Super-highly recommended. read more

We recently purchased a new construction home. The home itself was great, but the backyard looked to have drainage issues. Allied Waterproofing was responsive, honest, professional and super knowledgeable. Would highly recommend! read more

I have never been so happy to part with my money. No, seriously. We've had some basement water intrusion issues. When I first had Paul out, he was very conservative and gave me some (free) practical solutions for things I might try before a more costly solution. Other folks who came out to bid gave me wildly different suggestions that now, in hindsight, if I went with I would not have solved the problem. Instead, Paul suggested I try those things and then wait to make sure the problem was what we thought it was. I'm so glad I followed his guidance. That period allowed us to really understand what was happening. When it became clear I needed more help, he came out not once but twice more when I needed extra assurance and a second look at his bids. He bid significantly lower than the other contractors who came out. Beyond that, he was kind and professional and I knew he was the right guy for the job. When it came to the actual work, Paul and his crew were on time, professional, and finished the job in less time than quoted. The finish work was immaculate and the crew cleaned up after themselves -- not just when the job was done but also each night. In the end, we have a foundation footing drain and a that room is now perfectly dry. Every time we hear the sump pump working (which we only hear if we're outside and standing next to it), my husband look at each other and say... we love that sound! So much better than a flooded basement. I recently has another (unrelated) ground water issue and emailed Paul at midnight on a Sunday night. His response was to my inbox at 7 AM the next day and he's prioritized coming out to take a look at this separate problem. I am so grateful for Paul and his team and couldn't recommend them higher to anyone needing work done! read more

I worked with Paul. Assume it is the same company but I do not think they are based out of seattle. Paul and his crew were great. Reasonable quote, they fit me on the schedule in a reasonable amount of time, job was done as they described, faster than they predicted, cleaned up afterwards, and no surprise costs at the end. Best, yet, I write this review a year after the work and my basement has been dry through the winter.

Allied waterproofing ( Paul) stopped by to give us a quote and assessment for water in our basement. We had lots of water coming in , continuously over the last few months even with dry weather and no rain. We got quotes from other vendors, used a leak consultant to ensure it was not our pipes. Paul looked at the issue, listened to us and asked us to check our air conditioning unit. Though there was water seeping into the entire room- he shared that he has seen this happen before and we should check that anyways to make sure, though he would give us a quote anyways. What a lifesaver, it did turn out to be a leaking tube at the back of the air conditioning unit/ furnace where the water was traveling along the seam of the wall/ floor and coming into the room at a different point. He saved us a lot of money as the fix was $300 versus a major waterproofing effort for that part of the room. Love the integrity of this business. They get booked up very fast- we waited a month for an appointment- worth it. read more

I had an estimate done by Bodine to install drainage in my crawlspace and the price was out of this world for a 900 square foot house. Paul came out and bid the project at half the cost and provided the time when they could complete the project. They were on time and did an excellent job at finishing the crawl space and making the yard look like they we're never there (for drainpipe to curb). I'd definitely recommend, timely, fair bid, and clean work. read more

I was impressed with the straight forward, educational bidding process. Paul was very knowledgable and the price was fair. Project started and finished on time. The crew was extremely conscientious around the house. They protected my floors and furniture and left the place looking better than when they started. They were efficient and each day I was impressed with the amount of work they got done. The workmanship is top notch. I would not hesitate to recommend this company! read more

I contacted Allied Waterproofing and Drainage on a Monday afternoon for a quote to fix my french drain and they were able to send someone out the very next morning to take a look at the drainage problem in my backyard. I explained to Paul, the person they sent out to take a look at the problem, the work I had already done and he quickly suggested a fix. The fix involved a lot of shoveling, but less work than I had anticipated. Paul still sent me the quote I requested, but after hearing his advice, I decided to address the problem myself. I really appreciate how prompt, honest and straight-forward the company was when I asked for help. I would definitely recommend contacting them if you have drainage problems! read more

Allied came out again to finish waterproofing our basement. We did have a couple leaks where they didn't work originally. The second time they were great as the first time, the guys still took away some extra concrete debris of ours. I recommend these folks! If you want honest, hardworking people to fix your drainage issues, these are the people to go to. I appreciated the cautious approach, buf we have been totally dry! read more

These guys replaced our 100plus year old sewer, I can't say enough about them. They were hardworking, super nice, and did a wonderful job I highly recommend them. read more

After meeting with about 6 other plumbing businesses, I went with Allied for a channel drain installation outside our garage door. Paul came out a few times, answered all of my questions, was prompt with emails and phone calls, and offered a very competitive bid. The work was top notch, with one minor issue of slope - which turns out was not in scope of our project (hence the 4 stars instead of 5) - that they will be fixing soon. Very pleased with the work, friendliness, and professionalism. If you need any sewer work done, this is the place to go with! read more

This company is professional. They got my drainage issue resolved with a perfect solution and fair price. Highly recommend them!

Hands down, the best experience I've ever had with a contractor - can't recommend them enough. Paul and team at Allied Waterproofing put in a new sewer liner for our house. Things that made my experience great: 1) Professionalism: Paul, our Estimator, was incredibly responsive. He quickly provided a quote for the work that provided a very detailed explanation of the work that was needed. Other contractors just gave me a number (no details). Paul also replied to my questions via e-mail quickly and thoroughly. 2) Cost: Paul's bid came in at 30% less / thousands of dollars lower than bids I received from other larger plumbing shops. I was worried that the lower price point might mean low quality work but other online reviews reported fantastic work so we chose to move forward. I'm extremely happy we did as... 3) Quality of work: Most important of all, they got the job done right and their attention to detail was excellent. They got the new sewer liner in quickly and with minimal disruptions at our house. When the team found an unexpected break in our sewer line, they dug right in and replaced the broken piece of pipe instead of leaving the problem to fix later. Despite having to dig several large holes in our yard, they restored everything perfectly - I literally think our yard looks better now than when they started. In all, if you need sewer / drainage work, go with these guys. Very professional, great price, great work. read more

This company absolutely amazes me. I have water coming under my foundation. Amongst many other issues. Paul(the owner) came out probably 10 times over the course of a few months presenting my with options at zero pressure. Turned out I needed all my curregated downspout pipes replaced. I can't thank Paul enough for his patience. This is unheard of in Seattle. I had every drainage company out in the area. By far Pauls customer service and transparency are superior. And prices are fair. I will only trust my drainage to allied from here on out. The team that came worked hard and fast and cleaned up everything. There were areas I wanted dug by hand which they did no complaints. Amazing company. read more

A professional and hard-working team who did a thorough job. Upon checking their own work, they also found another issue unknown to us that is simple to solve but was off of our radar. Would recommend! read more

We asked for a crawl space inspection to address our concern about sagging insulation. They were very prompt scheduling, coming in on time, and being very honest to tell us that we don't need any repair beyond just stapling some cardboard back to the vent window top. Having dealt with a lot of contractors lately, this is a breath of fresh air! read more

Paul came to my house to assess potential water leaks in some areas of my patio and garage. He did a thorough evaluation and was very nice and didactic along the way. I was able to understand exactly what needed to happen. Damages were minor in my case, but still he went above and beyond and recommended many contractors that could help me tackle the issues. Overall, I am really satisfied with his services and would recommend hiring him to anyone looking to evaluate and solve these kind of issues. read more

I wish I could give more than 5 stars. We have dealt with a wet side yard for a number of years always thinking we'll get it corrected some day, even after having water come through the garage a couple of times and buying a sump for the low spots to use during very rainy times (which sometimes meant middle of the night pumpings). I know, stupid huh? Always thought it would take a major drainage procedure to move dirt around to have the water drain elsewhere etc. Finally had to bite the bullet. Checked on yelp and found these guys. They gave a quick estimate and had available time within a couple weeks. Instead of major dirt moving, they showed us where they could just go down from the lowest spot and pipe to the catch basin in the street. Paul had guys out when he said, two guys put in a couple of hard days digging by hand (as all house electricity, cable and gas were in the same area), through hard pan, down a couple feet, put in everything they needed along with some cement work and completed in two days. I could not believe when my wife called me at work to tell me it was done so fast. And it works fantastically. Our first hard rain, we had to check it out and sure enough, worked like a champ. Paul was a great guy to work with, and always kept us in the know of how things were going. Please give these guys your business, you won't be sorry. read more

We have had chronic water problems in our basement for years. Paul at Allied Waterproofing was recommended and we were very happy with their work. Good price, quick turn around and our basement has been bone-dry all year. We had them return about 6 months later to replace part of a sewer pipe that had roots in it. Again, good price, quick work and happy customers. I highly recommend them. read more
