"It’s been a while that I wanted to have a company that can come over and check the house for any problems that increased my monthly bills and to fix them at a normal price. I came across this company and I scheduled a meeting with Ezra and Charlie to come over and see/check. Ezra and Charlie checked the house for more than 2 hours and they found out that some of the windows were old and needed to be replaced with new ones. In addition to that, they recommended me to remove the water heater and to install a tankless system that will provide me with hot water only when I need and by having that, my bills will be reduced.The Quote that I got from him was good enough (to my opinion) and I retained them for the job. The work that they did proved to be good one and I see that in my monthly bills. It was a 2 weeks work and I am completely happy with my decision to hire them."

"Building this balcony was one of the best decisions I?ve made for my home. There was nothing there before just a plain wall. I love reading and I felt like I truly deserved this space. Expert Home Builders were my ally; they really nailed it from the structure to the finishing touches. You have no idea how much this balcony has changed my life, mornings and evenings are just spectacular from here"

"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.

I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

"Matt came to inspect our roof and found another tile that needed to be replaced in addition to the 2 that were already broken. He came the next day to do the job. In addition to replacing the tiles, he fixed other tiles that were previously repaired by another company. He was efficient and did an awesome job. Reasonable price and would use him again for any future jobs."

"I went with Expert Home Builders on a room addition. The big and expensive project and bog responsibility but I'm happy I hired this contractor. David and his team showed up on time and they were great from first day to end of this project. David was knowledgeable, honest and helpful. He informed me about working progress all the time and contacted me immediately if there was something important. His team worked hard, kept working area clean as possible, they were professional, friendly and quick also. The project was finished ahead of schedule and results are excellent. The quality of work is superb, overall experience excellent and price very acceptable. I would highly recommend Expert Home Builders to all people I know!"

"We loved working with Repair and Remodel Experts. They were
professional, polite, accommodating and stayed on task. They met our
deadline and the work they did was fantastic. Being a church, we
appreciated their work ethic and the demeanor of their crew. We didn't
have to worry that we would have visitors who might hear inappropriate
behavior or language coming from the construction area (which was right
next to our current office space.

"Amanda from Homemade design provided me with a variety of suggestions for couches, end-tables, lamps, window coverings, rugs, paints, accessories to match my style and color preferences for my living room. Amanda has better than great ideas and worked to stay within my budget. I also hired Amanda to design my kitchen, dining room, game room, and master bedroom and bath. Building and furnishing a house is a daunting task, and Amanda was a great help in putting it all together. I couldn't have done it without her. Well done Amanda! Would I recommend Amanda? Yes Yes Yes!!"

FAQs for addition to existing structure building service projects in Fort Irwin, CA

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.
