"Fantastically well. The quality of the work performed was top notch and the individuals on the team were highly professional and very personable. The lead, Samuel Nelson, listened carefully to everything that I said and then provided valuable feedback that resulted in a better outcome and lower overall cost. I am more than pleased to be able to recommend Nelson General Contractor."

"It was a wonderful experience. Matt knew what he was doing. He listened to what we wanted and made sure we got what we wanted. He had suggested we visit a Cabinet maker store in Lancaster and after doing that we found the perfect cabinets for us. His work is excellent. He is very efficient and neat. Even with our changes he was able to maintain and keep the project on schedule. On a personal level he and his helper were very nice. I would highly recommend Matt to anyone and we are having him come back to do other projects."

"Adding space to our home felt overwhelming at first. This was not just cosmetic work?it involved structural changes, inspections, and multiple stages of construction. We needed a team we could truly trust. BMR BelMax Remodeling handled everything with professionalism and steady communication. Even during the more complex phases, we felt informed and confident that things were moving in the right direction. The finished addition blends perfectly with the existing house?it does not feel like something that was ?added on.? It feels natural, like it has always been part of our home. The extra space has completely changed how we live day to day, and we?re grateful for the care and effort they put into making it happen."

"We worked with Gary at Legacy Construction Company to replace the rear roof and siding on our upper floor, along with two windows, and are very pleased with the work he and his team did. Gary took time to explain the pros and cons of our options, provided siding samples and was communicative and responsive. The invoicing and payment schedule was straightforward and easy to use. The work is high quality (having survived multiple rainstorm and snowstorms at this point!), and the team was able to do it in a day once all the materials were ready, making our lives much easier. The adage “you get what you pay for” holds true; Legacy Construction was worth every penny and we are considering them for future renovations."

Work was completed to a very high standard and the job progressed according to the expected timeline.

"Couldn’t recommend highly enough! Rick and his team did an excellent job completing several projects in our home including building a gym in the previously unfinished section of our basement, transforming a den into a bar room for entertaining, and coming up with a creative and perfect solution to put an office in our basement. Rick is a great, trustworthy guy and does beautiful work!"

"On Call Contracting is amazing! Prompt, affordable service for our growing family. We needed our kitchen done (including removing walls) and John was our guy! The entire process went so smooth and the results are beautiful. We had an out dated kitchen from 1960 and On Call helped us design, remove, re-build, and install our new kitchen cabinets and everything! Couldnt be happier and would highly recommend!"

FAQs for addition to existing structure building service projects in North Wales, 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.
