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!!"

"Legacy Remodeling did an awesome job to our bathrooms and family room. It turned out beautifully and was completed on time. After meeting up with Alvaro (owner) several times to discuss the projects, we decided to hire him. The best part about this renovation was that Alvaro did the work himself with very good eye on details, as well he is very knowledgeable on plumbing, tiles, carpentry and electrical. Also, he has a great crew. Often, they worked weekends and stayed late. We were very happy with Alvaro and his crew and, we plan to hire them again soon for our next house project."

Basement Leak Repair questions, answered by experts

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

You may have to dig out drain valves if they are buried under dirt. This method isn’t ideal, and it increases the chance of clogs and damage. Ideally, a drip irrigation system buries drain valves in a gravel pocket so they are easier to access and better-protected. If you have trouble accessing drain valves, hire a sprinkler professional to find them safely and efficiently.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.
