Super Service Award Winner for Last 4 Years in a Row! Celebrating 33 years as a carpenter on Cape Cod in 2017. I am experienced in all phases of carpentry. I am self employed and do the majority off the work myself. I have low over head and minimal subcontractors. This will assure you of a quality, cost effective project. I will be there to communicate with you “one on one” should there be any questions or concerns throughout the duration of the job. Additional website: http://capehomeremodel.com/.

"My family and I hired Jeff as our General Contractor to oversee the construction of our 1500 sq. ft. summer home. It was the best decision we made regarding this project. Jeff was a pleasure to work with. He was attentive to our design requests and of our vision for this home, while providing his expertise in all phases of construction from site work, foundation, framing, siding and roofing, stairs, and all interior finished work – including installing wood molding trim, doors, closets shelves, kitchen cabinets, bathroom vanities, all of which he does himself. Jeff hired and coordinated reputable subcontractors required to complete the project on schedule, and met all of his commitments regarding price, quality of materials, and high standard of professionalism and quality construction. Jeff was responsive over the 6-month schedule, keeping us informed of the overall progress, including subcontractor and weather delays, local permitting challenges, and coordination of several building inspections – all of which passed the first time attesting to the quality of Jeff’s work. Overall, whether it is a large or a small project, we wholeheartedly recommend Jeff for your construction project."

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

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

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.

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.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable.
