We are family owned and operated since 1952, provides home repair construction services in Delaware, Montgomery and Chester Counties as well as New Jersey and have been providing residential and commercial renovations and remodeling to the surrounding community ever since. We specialize in basement remodeling and conversions, windows, garage doors, fire and water damage, and many other reliable contracting services. Let our reputation of doing whatever it takes to get your job done on time, on budget, and to your satisfaction give you peace of mind. Our engineering background means we accomplish what others say is impossible. We always focused on our client goals and delivering high value outcomes.

"The garage was crushed by a huge tree, so we needed demolition, debris removal, and a new garage, plus other storm damage repairs. We contacted several contractors, and D.Willis was among the first to arrive, and offered the widest scope of skills for the job, including handling permits -- one contractor who could do everything for the work. They brought in an excellent team of builders who worked efficiently together. As new damages were discovered during repairs, they were amenable to take on the additional work and renegotiate the contract as needed. Finally, the work completed a bit beyond the contracted terms, with good attention to details."

FAQs for addition to existing structure building service projects in Glen Mills, PA

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
