Northwest Exterior Residential Drainage Services

There are a few types of exterior residential drainage services or systems that are used here in the Northwest. These systems are tried and true and are very effective of moving water away from your home. Seattle area homes with or without basements seem to collect water during the winter. With over 30 years experiance, we have come to rely on. Here they are:

French Drains

French drains have been around forever. However, they can be tricky to design and install. This is where our years of experience come into play. Hidden obstacles like tree roots, pipes, power-lines and sprinkler lines are just some of the challenges that we look for when designing a french drain system for your home.

Perma Dry Drainage Solutions
When you live in the Pacific Northwest, you expect a lot of rain to fall. But when your home or business develops water damage, you need a reliable way and a reliable company to solve the problem.

If you need a long-lasting solution to basement drainage for your property, call Perma Dry Waterproofing and Drainage at the first signs of trouble. We cover primarily from Bellingham to Olympia but will travel further to help in all directions. We have many clients on the East side of the mountains and South beyond Olympia.

Prevent Indoor Water Damage
You may not think to look outside for drainage issues when your basement is flooded or leaking. However, at Perma-Dry, we look both outdoors and indoors so we can properly assess and determine with clarity the conditions creating the water intrusion source.

If we can install a more cost effective superior drainage system outside then that will be our recommendation. It is definitely in some cases a smarter way to keep water from entering the basement or crawl space. Again, it is trusting that a common sense approach while paying attention to all the details of each unique situation is taken into consideration.

Some companies only take a surface view of your drainage problems before offering their cookie cutter and sometimes temporary fix to address difficult issues. Our field representatives do whatever it takes to find the issues and discuss all options with each client to determine the correct repair whether that repair is either inside or outside. If that means crawling underneath your home, opening your sheetrock/drywall to find an internal leak, or following up post diagnostic services we’ll do it.

We believe our clients deserve more than a vague answer about their repair or system design prior to investing potentially thousands making that repair. Once we determine the source and drainage needs, we’ll give you honest advice about the steps you should take, which sometimes doesn’t even include our Perma Dry team.

We don’t sell solutions…..we solve water problems guaranteed.
