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."

Timson Builders, Ltd., has been helping homeowners and businesses in Chester, Delaware and Montgomery counties realize their dreams for over 30 years. Whether the job is a small specialized residential renovation or a major commercial construction project, it will receive the same attention to detail and budget. As fully-licensed and insured on-site general contractor, we manage a team of skilled, professional subcontractors who understand our commitment to the highest quality craftsmanship. Our reputation for exceeding homeowners' and architect's expectations has resulted in a legacy of referrals and satisfied customers. Let us meet with you to show some examples of our diverse portfolio and talk about how we can help you realize your construction goals.

"We found Stan on Angiâ s List for a remodel of our unfinished basement and we were impressed with his knowledge, his ideas, and his commitment to doing quality work. When we first met, we told him that we had a baby on the way and were working with a tight window to hopefully complete the project before the baby was born. We hired him and we knew that we made the correct decision because he was determined to make that deadline (and he did). Stan also worked with us on our budget and helped us cut where we needed to in order to make our dream basement come true. He handled all of the permits and talked with the borough for us so we didnâ t have to deal with that headache which made the process so much quicker and easier. That was very important to us. Lastly, even though our project was smaller in comparison to what he normally does, we didnâ t feel like he cared about our project any less than others. The commitment and care did not go unnoticed. Thank you Stan for making our basement beautiful for our new family. Highly recommend!"

FAQs for addition to existing structure building service projects in Kennett Square, 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.
