    flooding window well
    Michael H.

    Good contractors, absolutely terrible management, follow-through, and design. They signed on to our egress and waterproofing project in late 2019 and here we are, in December of 2020, and we still aren't done. This is because: 1. Without asking us they changed all the permit drawings, and submitted a design that would not work. We had to resubmit the original drawings after we found out about the changes and called out their mistakes. 2. The ordered all the wrong size windows and had to delay the project 2 months farther 3. They still have not installed ladders, window well covers, or hooked up the drains for the window wells. Because of this, our window wells have filled with water and the siding and wall assembly is getting soaked. I'll update this review to describe the problems in more detail later, but for now I need to stop my basement from flooding. Only reason I didn't give them 1 star was their workers and laborers, who are skilled, kind, and hard working. They're stuck with a terrible management structure, but every time Terra Firma has been able to get the right materials and plans together to actually perform the work we're paying them for the craftsmanship has been top notch.

    Porch Repair
    Jim S.

    I had a sinking porch and sinking driveway. I had addressed the porch with another company about 7 years ago and they were completely out of the ballpark for just the porch repair. Our driveway became a problem over the last couple of years and my wife stumbled over the trip hazard more than once and begged me to find a way to solve this. I located TerraFirma and asked for a quote. The associate that came on sight was amazing - his presentation was so good, I cancelled the appointment for a second quote and asked TerraFirma to do the project. BTW - they were 1/3 the price for the entire project from what the other company quoted 7 years ago for just the porch. The technicians arrived today and from start to finish were grade A++. I would do a commercial for this company - best experience ever!

    If I could give them 10 stars, I would. Richard Stewart was our sales person who came to our house to look at our problem and give us a quote, Bree Larson was our customer service rep, and Colin was the leading man in our actual repair. We are new home owners, who had ground water intrusion and straight up FLOODING in our basement right after month 2 of moving in. We did hours and hours of research, had at least 10 companies come to look at the problem and give us their opinion/quote, before we decided on TerraFirma. Mind you we had literally no idea what to do and were just trying to follow our gut to choose the right company. Every step of the way Richard, Bree, and Colin were so kind, quick to respond, and so extremely knowledgable. We felt so safe in their hands and are so incredibly grateful to have our basement completely waterproofed. Colin waterproofed our retaining wall, dug interior drains around the perimeter of the problem rooms, and installed an underground sump pump that filters into our downspout outside of our house to pump the water out from underneath our home. Groundwater, and water in general, is an absolute nightmare and Colin knew everything - as well as took the time to walk us through and explain his work every step of the way. So thorough, so neat, we are elated. THANK YOU SO MUCH. Stop your search here, this is the company you want, hands down.

I contracted them to do a simple tear off and reroofing on my home and was told that it would be a 2-3-day job...It's been over 2 months and the job is still not done. The initial install was done so badly that the value of my home has been permanently diminished and it needs to be re-sheeted to make it right again. The MULTIPLE visits by their crews to correct the countless mistakes made, have all been half assed at best, they fix one thing and ignore several others, causing more delays and more scheduling conflicts. The lack of communication is infuriating, I've explained several times that we need to make arraignments for our pets prior to workers showing up, and continually they cannot be bothered. I guess working on the NEXT roof is more important than finishing mine. This was supposed to be done in July and we are halfway through October and weather is coming in fast. Sure, everyone has apologized, and they keep saying they will make it right, but in the meantime, I am still dealing with this aggravation, my house still has the scars of a horrible roofing job, and now I have missed my window of opportunity to repaint the home before winter sets in and will no doubt be facing increased costs for not repainting it in a timely fashion. Having to hiring another roofer to get my home ready for winter Don't do it! Find another roofing company.

    From when we first called PermaDry regarding french drains in the yard and an improved sump system…read morein 2015, to a major basement flood mitigation project in 2020, and through our last issue-free annual maintenance appointment in 2023, we've always thought that these were the folks to call. We've recommended them to countless friends and relatives over the years whenever homeowners in Seattle inevitably need help dealing with drainage issues. We've sung their praises to people on forums seeking help finding the best company to help them deal with drainage and repair jobs. Never again. Even if we set aside the fact that our last annual service appointment took almost 9 months (with four reschedules and three no-shows) to actually happen, this company is no longer even able to bill correctly for work that has been completed. We've now gotten three invoices in a row that are not only the incorrect amount, but they're for a bill that we paid in full back in February. They're not even system glitches for an old bill in the system: someone literally created a brand new invoice for the wrong amount and for services that we've already paid for, and they did it after we paid in full. No one ever answers the phone. No one calls back. We just keep getting texts with this wrong invoice over and over. The last response we had about this was in an email on April 1st, and all it said was that Ryan (the owner) had recently fired the back-end staff person who'd screwed up all the scheduling for 2024 and that he'd asked another person to handle the invoices. No apology, no attempt to resolve, and (most importantly) no follow up since then from anyone at PermaDry to actually fix the incorrect invoice that we keep receiving. We've stuck with the absolutely terrible customer service for over a year now because we didn't want to invalidate the warranty we have for the work they've done for us, and we've tried to have patience since they've done great work in the past. At this point, though, it's probably going to be better in the long run for us to just let that go and move on to picking someone else for future household needs. Do yourself a favor and choose another company.
