"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."

"Adam did an excellent job building our garage from the ground up. He was excellent to work with. Not only was he very professional, so were the subcontractors that he hired. Everyone was knowledgeable, helpful and friendly. Our project required that a road be built to accommodate large trucks in the springtime. The project stayed on track and proceeded smoothly. We were never left wondering “what’s next?” Adam has great communication and stayed in touch to make sure we knew what was coming up and when. I would definitely recommend using Magic Frog Carpentry."

"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!!"

Basement Remodel FAQs, answered by experts

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

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.

Save money on your basement finishing project by making cost-effective decisions such as minimizing structural changes and avoiding costly construction revisions. DIY simpler tasks such as painting or basic cleanup to reduce labor costs. You can also opt for energy-efficient fixtures and materials that may qualify for rebates or tax incentives.

Key trends include home gyms, theatre rooms, additional rooms (bedroom/office), and more, with personalized styles reflecting individual preferences.
