"We are so happy that we hired Benchmark to remodel our kitchen! Lee and Ian were professional and knowledgeable, from beginning to end. We were very impressed with their attention to detail. They made our 1980's dingy, dark kitchen look amazing with beautiful white cabinets and granite countertops. We love it! I highly recommend Benchmark and will recommend them to my family and friends. Thank you, Lee and Ian! Sallie and Don M."

"When you find a great contractor, don’t let them go. ;). I hired Tim to build a screen porch under my deck but added several projects as I recognized the high quality of work and attention to detail from his crew. In addition to the screen porch, they built a deck extension - so nice that I decided to have them replace the existing deck, installed a basement slider and replaced the door, installed a new fence and built a shed. Tim was responsive, open, honest and receptive of my requests and additions during the project. Great experience working with Tim and his crew: Dan, Brian, Eddie and Ben. Great job on all the work - I’ve received many compliments from neighbors and guests on the work you did! I can’t recommend Tim and his crew enough."

"We have been wanting to finish our basement for a very long time now but the prices we were given were too high! A friend of ours referred DCL to us and we thought we would give them a shot. The price was right so we started shortly after. They took care of all the paperwork and permits needed! Bob was there for the whole process discussing with us every step of the remodel! Very knowledgable and very well trained team! Our basement looks incredible and we enjoy spending time there! I would recommend DCL to anyone!!"

"I needed the backsplash in my kitchen done professionally since I chose tile, which is not something I could do. Torin fit my smaller project in , between his bigger outdoor projects. He was very professional, offered suggestions, did a great job, both installing and cleaning up each day so as not to disrupt my kitchen usage. His measurements and quantities were spot on( I was ordering the tile myself). I will definitely call him for my next project. His quote and finished price were almost spot on and very reasonable. I highly recommend him for anything you need done!"

"Our bathroom remodel was a huge task and Costas, Tony, and Pauly did a great job! Very easy to work with and we never minded having them in our house. Their initial quote was exactly what we paid! Definitely recommend and will hire them for future jobs!"

"Jim was a consummate professional from start to finish. He gave a very detailed quote, patiently answered all our questions, and started the project weeks before we ever thought we'd get a contractor to start. The work was fantastic. Our basement came out beautiful and Jim was a pleasure to work with. He did everything exactly as designed, communicated progress, and was very responsive if we needed anything. He was also very knowledgeable about the various options for finishes, flooring options, etc, and even had some contacts with local businesses that gave us good prices for some of the materials. I highly recommend Hamil Improvement for any remodeling project. Would definitely work with them again!"

Basement Remodel questions, answered by experts

Create a checklist, reimagine the space use, set a realistic budget, choose materials and aesthetic details, and get professional support for guidelines and troubleshooting.

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. 

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.

You should always use high-quality lumber for your framing in order to ensure it will last the test of time and resist moisture. Use 2-foot by 4-foot lumber that is pressure-treated for your framing.
