"If you’re thinking about getting a new roof, definitely go with Build Atlas. I’m in my mid-20s and had no idea where to even start, but a neighbor recommended them and I’m so glad that they did! The whole team was super friendly, down-to-earth, and made the entire process way less stressful than I imagined. They showed up when they said they would, kept everything clean, and finished faster than I expected. Plus, the roof looks fantastic — it’s like my house got a facelift! It’s rare to find a company that’s this easy to work with!"

"As a busy local Realtor, I know that finding good contractors is tough. I highly recommend Lamorinda Build for any home improvement or repair work! Over the past year, Rickâ s helped me with a variety of projects around my home and my clientsâ ; electrical updates, rodent proofing, fixing misaligned doors, etc. Each time, heâ s proven to be reliable, skilled, and easy to work with. What stands out most about Rick is his attention to detail and commitment to getting the job done right. He takes pride in his work and always checks to make sure Iâ m happy with the results. Not only is he professional, but he also brings a friendly, approachable attitude that makes working with him a pleasure. If youâ re looking for a trustworthy and hardworking contractor, Lamorinda Build is definitely the one to call. Iâ ll be reaching out to him for all my future projects."

"It was a design and build project: a 1200 sq ft 2-story addition to an existing house - two bedrooms, three baths, family room with wet bar, and office. Also a new 2-car garage. Matt Kennedy creatively designed the connection so as to access an existing 2nd story bedroom to the new hallway which connected it to one of the two new bathrooms. Robert Cerletti chose and managed very well the various subcontractors who were mostly expert professionals in their specialties - foundation, building structure, roofing, HVAC, plumbing, electrical, stucco and painting, wood/tile/carpeted flooring, and all finishing touches. From experience they knew how to work with city planners to reduce time for permit issuances. They recommended some added special features such as crown moulding, ornate wood stair railings, custom bathroom fixtures, exterior French water drainage, and quality kitchenette cabinets in the family room. From start to finish the project completed on-time within 9 months - delayed only by some unexpected heavy rains at the beginning slowing some foundation work. Six months has now passed since project completion and I could not be more pleased with the new addition. Robert Cerletti was on site frequently, checking on subcontractor work, consulting with me for input, discussing suggestions and ideas, getting progress payments, and paying his subs on time. The project completed on budget except where I specified added work beyond plan. I highly recommend Cerletti and Kennedy for similar projects small or large."

"After meeting with around 10 contractors, I decided to go with EA Homebuilders. Eric seemed honest and willing to do our remodeling the way we wanted it done. Great decision. Eric, Hector and crew were courteous and finished the job in the time they said it would be done, less than a month. We love our new bath/ shower. Highly recommend and would use again."

"It was a great pleasure working with Pouria and Juan. I hired them to help build a 400 sq. ft. deck, and they were able to finish it within a week at a very high quality. They were incredibly flexible with all of our requirements?don't hesitate to communicate with them if you need anything changed during construction! They are absolutely amazing and efficient. They even did some extra work around our house, which will really help us in the long run. Their pricing is very fair compared to many other groups, and I will definitely go to them the next time I need a project done!"

"Mastersuite remodel - created separate office within existing floorspace by adjusting bathroom and closet size. Great experience from start to finish. Ohad Mahoul, owner of Quartz, is very easy to work with, made helpful recommendations for material supplies, regularly visited our home throughout the project and responded very swiftly to calls and emails from start to finish; Ohad’s foreman, Luis, and co-workers, all worked tidily, respectfully and professionally - they were all very pleasant to have around. We made a few adjustments to our project along the way, which the team were happy to accommodate - nothing was too much trouble. The job required plumbing, electrical, lighting, carpentry, bathroom tiling, quartz counter and shower installation, installation of both engineered wood and tiled flooring. We are delighted with the results and are hoping to work with Quartz again on another project at our home."

"Definitely recommend to hire those guys We were looking to get our new house that was build on 1962 done, giving it a modern look before moving in. what made it more complicated is we had to get it done fast as we work from home and had only 2 months before our sons school starts and the project would of been pushed for another year. Ben with Creekside Pro Construction took us through the entire process, paying attention to the small details and to our needs. He explained us everything thatâ s was happening and with everything inspection that was done. What really helped to get it done fast is that they planned right. they pulled the permits in advance, helped us with purchasing materials and actually assigned their interior designer to shop with us. Overall, Very nice crew, great craftsmanship and excellent communication. Finished right on time and that with getting cleaner service before giving the keys back Thank you creekside weâ d definitely recommend you for family and friends! Sean and Amalia"

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

While your game room design is entirely up to you, people tend to include a few common elements in their game rooms. These may include pool tables, TVs, comfy couches, gaming consoles, and extras like home bars, arcade games, and sound systems with multiple speakers. Unique lighting and themed decor add to the gaming atmosphere.

If you want your game room to include both video games and movies, the cost of a home theater runs between $1,000 and $10,000. This cost estimate includes wiring, cable concealment, and other components like surround sound speakers, video screens, or video projectors. Higher-end equipment can cost considerably more. Budget for comfortable seating and tables for snacks to complete the home theater experience.

Chances are your game room could get a little rowdy at times, so you may want to invest in soundproofing the room for the sake of your family and housemates. The cost to soundproof a room ranges between $1,000 and $2,600, depending on the room size. “In certain circumstances, you might need to consult a sound engineer for optimum results,” says Ezra Laniado, owner of Landmark Construction & Development Group, Inc. in Los Angeles.

Along with converting a finished room or unfinished basement into a game room, another popular option is turning a shed into a gaming room. Some key considerations here are similar to converting a garage into a game room. The walls may need finishing, as well as factors like insulation, electrical components, lighting, and HVAC. You will need a fairly sizable shed for activities like billiards or table tennis.
