"Great results from waterproofing. Turned my spring flooding anxiety to calm. As humidity rose in summer, I put in a small dehumidifier. Made basement noisy as it struggled to dry and produced a lot of heat. As temperatures rose to about 83 down there and the humidity rose to over 68%, I had same people put in a whole basement commercial-grade dehumidifier. The small unit dropped the humidity to around 50% in less than an hour. Incredible performance and have me peace of mind and peace and quiet downstairs. Temperature dropped gas as well. Weel worth the price to save my most expensive investment."

Customers say: Quick response

"We used Lasting Strength to perform a major renovation on a 1950's basement living/bathroom area. The project was literally a complete tear down and start back over. Adam & his team of professionals were attentive to all details, such as plumbing/electrical and accommodating daily life needs. They worked around our schedules and also accommodated the management of the project via the use of technology (FaceTime, text, email), which allowed for quick decision making and allowed us to view items as they were found. From the plumbers, Sheetrock, painting, and electrical - the final product is exemplary!"

"There are not enough great things I can share about HammerTime Construction, and every single member of their team. From consultation to project completion, the high level of professionalism, expertise, SKILL, attention to detail, and superior craftsmanship was exemplary! We contacted William via Angi (blindly!) in hopes of helping my elderly parents restore their kitchen, and he agreed to come by that same day - a weekend- to do an assessment, and provide a quote. He assured us he'd work within our budget, and he stuck to his word. We were in constant contact for everything from project concept to contract to which materials we'd be selecting. Our expectations were surpassed 10-fold!! Hire them. Just look at the photos! Our parents' home was completely transformed in the best possible way. It will now be a source of pride and an enjoyable gathering space for all who visit. On top of the kitchen remodel, they also restored our hardwood floors to a beautiful state we didn't even know was possible. Miguel, Ignacio and the entire team were speedy, efficient and completely caring as though this were their own family's home. We will be returning to this company for future projects, and we recommend them with zero hesitation!!"
This was a larger bathroom with two accent walls, a tub and sauna shower with jetted shower heads, a custom-cut ceiling, heated pebble flooring, and a mini wooden walkway.
The client wanted a tub sitting on pebble stones with an accent wall, wooden look custom shelving, and a smart floating toilet.
The image showcases a contemporary stand-up shower featuring frameless glass doors that provide a seamless, open look. The interior is adorned with large marble tiles in a soft, neutral tone, giving the shower a luxurious feel.

Built-in niches provide stylish and practical storage for toiletries, while subtle LED lighting enhances the overall ambiance.

"Customer Service was by far above expectations. I felt my basement was as important to Pella as it was to me. Also, we were given great recommendations throughout the process. Quality of the work was very good. Only area for improvement was that the upfront estimate had a couple minor misses, and I would have liked the laminate planks to have been laid with 3-4 row repeating pattern rather than a 2 row; but I never made that expectation known upfront. Overall an excellent experience and I highly recommend!"

Basement Remodel FAQs, answered by experts

Envision the type of bar experience you'd like to create for your guests. For example:

  • Does your basement have enough finished space for bar stools or seating?

  • What type of additional lighting would set the tone for the room?

  • Are there basement windows or an HVAC system?

  • Do you need new plumbing in your basement for a proper wet bar?

  • Could you be happy with a built-in wall cabinet bar rather than a full-scale wet bar?

Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms. 

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.

Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.
