"Anton was easy to work with. Sent email on a Sunday. He called in five minutes and came that afternoon to look at the job. Replaced baseboard in four bedrooms and repaired a hole in the ceiling. All work was completed in two days starting that Monday. The carpenter that did the baseboards (I think his name is John) was great, neat and did a wonderful job. I will definately call Anton again.

"We had an idea and the owner, Bud, had a vision!!!! He created an absolutely beautiful outdoor living space.... multiple levels and entertainment areas. The space is gorgeous and every level of detail from the wood work to the design to the layout to the built in bar is just beautiful and functional! Bud provides a level of experience like no other. He is onsite and manages all his subcontractors and expects a superior product which is what he delivered."

As a new home owner, Dave was more than willing to guide me in the right direction and was more than accommodating when changes were made.

"I recently had the pleasure of working with Miguel and his team on a major renovation of my house, which took about five months to complete. Throughout the entire process, Miguel was incredibly patient and attentive, ensuring that everything was done to the highest standards. His workers were always punctual, professional, and dedicated to their work. The quality of the renovation is outstanding, and I couldn't be happier with the results. Even now, if I run into any small issues, Miguel is always willing to come by and check it out, promptly fixing any problems. I highly recommend Miguel and his team for any renovation projects."

"Gustavo and his team were phenomenal. The scope of the project evolved a lot after starting yet Gustavo was extremely fair with the pricing and tried his best to stick to the original timeline. His ethics are unmatched and did not deviate at all from his original quote for the initial job. From the day he started, you could tell Gustavo's primary objective was to ensure 100% satisfaction when it comes to quality and value. There was a fair amount of structural work such as removing a load bearing wall and replacing it with a complicated support beam. The final result looked like the house was originally built like this. So from the structural elements all the way down to the bathroom tile grouting everything was done with expert precision. Was also amazed to see how tidy his crew kept the house and cleaned up every single day and didn't damage a thing during the 6m renovation. He even helped out with minor things around the house outside of the renovation project which he did with full care. Couldn't recommend Gustavo and his team more. Can never go wrong hiring a great person who gives 100% to deliver."

"I've used Champion for many years and for many projects. Kitchens, bathrooms, interior and exterior painting, flooring, roofing, bathrooms, decks and window installations. I have never had an issue with them. Their work is clean, they are reliable and the workers are genuinely nice people. This time it was to remove my old deck and build a new composite deck, paint trim and do some trim carpentry. All done perfectly. If you want a contractor that treats your house like it was theirs then give them a call."

"It went very well. Inson always focused on the highest quality products that would fit the design. Also tried to get each item at the better price. Additionally he was meticulous with the project and **** ** the vendors to make no mistakes and focus on a quality outcome. Finally Inson and his team were diligent to make sure everything was constructed in the right manner. In our case the proper wiring and safest plumbing. Always relied on master builders and plumbers who new what they were doing. The final outcome was above expectations. I would keep in mind any project like ours will cost money - we spent extra with Inson but in the end it was the right thing to do and well worth it."

"LRL Designs drew the blueprint, designed my kitchen & 2 bathrooms and created a new entrance to my dining room, which created a much more open floor plan in my main floor. I love the way everything turned out and am very grateful for the professionalism and dedication from the designer. She was a pleasure to work with."

FAQs for addition to existing structure building service projects in Yonkers, NY

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.
