"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

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

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. 

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

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.
