Allied Waterproofing & Drainage

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 .

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.

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!

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.

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!

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.

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.

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!

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!

I am very pleased with all aspects of the job. From estimate to scheduling to work, the project ran very smoothly. I had a crawl space drainage system installed with a sump pump. Hard working crew for sure.
