"Declan and his team installed tongue and groove wood on my covered porch. The team did an excellent job, with a focus on quality. The job took place over two days, and I was impressed both times with the crew. They started first thing in the morning, were respectful of my home, were very kind, and cleaned up SO well. They took care in picking the best pieces of wood during install, and asking if they had any concerns about a piece. They ensured two different sections of the ceiling were aligned, and it looked impeccable. I am very happy with my experience, and hope to use them in the future again!"

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 West Chester, PA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
