"We recently had our deck rebuilt by S&A Royalty, and the results were fantastic. They incorporated several improvements, including a Rain Escape system for a dry area underneath, an LVO beam to reduce the number of columns, upgraded materials, enhanced lighting, and a new ceiling soffit. The only downside was that the project took three months instead of the promised three weeks. Despite the delay, we are thrilled with our beautiful new deck and look forward to enjoying it for many years. "

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 Collegeville, 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.
