"Santiago and his team did an excellent job repainting one wall of our hardee plank outdoor siding. The wall had some damage from wood hardener and was very faded. It sparkles now with not trace of stain! Santiago arrived on time, completed the job in a timely manner and left the site spotless. We greatly appreciated Santiago's prompt response. We are selling our home and wanted the new buyers to love the home as much as we did. This project has brightened up a dull exterior and made the home so much more inviting. I would highly recommend Santiago for any job. (Also, his prices are reasonable.)"

We are a local Whatcom County family run business who specializes in residential remodels and additions. No project is too big or too small. We can do anything from siding, decks, fences, to bathroom and kitchen remodels. We also do ADU's DADU's and can help facilitate the permitting process.

"Paul Burlingame (and team) constructed a basement garage and attached ADU on the side of our 100 year old house - no small feat at all. Initially we were a little guarded because of all the horror stories you hear about shiesty contractors, but our experience with Paul has been nothing but positive throughout the entire build. He has a keen attention to detail and values good quality work. For example, there were a couple crucial details that were not described by our engineer, and Paul worked hard to determine the right course of action. In the end, what he came up with was better than we could have imagined. Not only is he personable and a knowledgeable contractor, he has an eye for aesthetic which was a delight as we discussed design options, from trim details to pergola hardware. In the end, Paul and his team built us a stunning 800 sf 2 story ADU and 400 sf basement garage, that feels spacious and contemporary while beautifully tying together with the exterior of our existing 1920s Tudor Revival home. I can not recommend Burlingame Contracting enough! Thank you Paul!!"

"James and his crew at Cox Custom Remodeling did a great job with our bathroom remodel. Our house was built in 1900 and the nonstandard framing made things more complicated. His lead, Dan was particularly great, taking the extra time to understand components we picked that were new to him. James always had a positive attitude, showed up when he indicated and got things done. Low dust, protection for floors and respect for the rest of the house while the construction was going on. James also provided the best tile guy, Eugene, that did a fantastic job with natural stone and the complicated very fragile mosaic. We would definitely use Cox Custom Remodeling again. Great job guys!"

Basement Leak Repair questions, answered by experts

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites
