Had a large, obtrusive puddle forming in my driveway every time it rained, which would stay there…read morefor 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.

Over the years, three out of four of our condo duplex units have had All Seasons fix drainage problems. We highly recommend these guys.

Unfortunately, I have to drop a negative review in the interest of warning other folks that their…read morework has gone downhill. I previously had an excellent experience with Terra Firma for management of a water problem in my crawlspace. I hired them without question again for my current property for management of moisture issues, and I didn't check their work upon completion as thoroughly as I should have. Unfortunately, about 1 - 2 months after completion of work, I discovered a large mushroom growing out of one of the structural posts in my crawl/basement. On closer inspection, I noticed that the dehumidifier water discharge line they installed was dumping less than a foot away from my foundation, corresponding to the exact spot the mushroom was growing. Moisture was the exact problem they were supposed to fix, but now they have created a severe structural problem secondary to moisture with the dehumidifier line dumping large quantities of water right next to my foundation. In other words, they created the exact issue they were purporting to fix by collecting the moisture and depositing it into my foundation. Once fruiting bodies are growing out of wood, this is an indicator that the wood is severely compromised and the fungus network has grown extensively. I now have a very expensive and serious problem to fix. I called to let them know about the problem, not sure if I will hear back from the coordinator/ the team who did the work. I am not sure if I would trust them to fix the issue after the damage they have caused, but I would accept financial remediation. If they take steps to make things right, I would update my review. I would not hire Terra Firma again for any crawlspace work, be it structural or moisture related because of the big problem they have caused. Again, just would like to warn others.

Bryce and his team at Seattle Drain Service did a fantastic job diagnosing our 1940s downspout and…read moredrain system that had gotten clogged after rainstorms. They carefully figured various issues (broken pipe on one downspout, a piece of downspout logged in another pipe and remaining kinds clogged), carefully fixed the issues and then ran the pipes clean to ensure everything worked and no new issues cropped up. They were quick and neat and reasonably priced especially compared to other companies who quoted just a one fix of a pressure wash which in our case would have caused more damage. Will use again if needed and definitely recommend.

Jo responded almost immediately with a bid based on the dimensions of our attic (he consulted the King County Parcel Viewer site to determine them). The other companies scheduled inspections.

However, when I compared the bids for equivalent services, Insulation Co was significantly less expensive. No 'special discount' required; just straightforward pricing. The crew arrived on time, were careful to protect our property, and did excellent work. They took photos of their work and reviewed them with me.
