"Picking Bridgestone Construction was the best decision I ever made! Jeremiah, the owner, came by and gave me an estimate for completely building me a new bathroom, started working exactly when they said they would, and charged me exactly what the quote was, not one penny more and got done on time! Jeremiah is extremely responsive, kind and understanding. All his workers are respectful and very nice. Jeremiah guided me through the entire process which made it comfortable and easy. I would recommend Bridgestone Construction to everyone. And for any job, the biggest or small. They were amazing."

"When I decided to remodel my kitchen, I wanted to create a look that was unique yet still very functional. To accomplish this goal, it was essential that I hired a contractor that adhered to the design. After receiving multiple project quotes, I hired Stone Age Design & Build. Once the project began, I found the crew to be real craftsmen, each performing skillful framing, electrical, plumbing, tiling, and cabinetry work. Every step of the way, the owner kept me informed of their progress, explained my options when questions arose, and made recommendations that best suited the situation. The finished product came out looking exactly the way I envisioned, and the only cost deviations (to the original quote) were the result of change orders I requested. I wholeheartedly recommend Stone Age Design & Build for any project that demand quality. The results will be used and enjoyed every day you’re in your home!"

"If you need an addition built on your house, I'd highly recommend you give Creative Remodeling a call. We used them to add a master suite which makes our house much more livable. We've also decided to add decking in the back yard off the the back of the house. Oh, and this was after working with them during Covid on a kitchen and 2 bathrooms. So that makes us repeat, on repeat, on repeat customers. The work is quick, to a good quality, and they listen to what the customer wants and have dealt with the odd snafu without any push back. Highly recommended."

"Our initial meeting with Suj was great. Initially, we had in mind a much larger job. He had quoted us $3000 for the closet demolition / wall rebuild (non-load bearing), packaged with several other items. Together with the fee for drawings ($4000) and permits, this was a bit higher than we anticipated. However, we decided to go with Suj due to his responsiveness and professionalism. Out of our other quotes, Suj’s pricing was middle of the pack - not the cheapest or most expensive. When the drawings were complete and evaluated, he gave us an updated cost of $6000 over text message. The scope of work had changed, and this was no longer part of a bigger project - understandable. The issue was when he gave us the official estimate a week later and up’d the price once again to $9000. When asked what happened, his exact words were “well, I need to get paid too”. He had weeks to consider before quoting the $6000 and nothing had changed since then. The extra $3000 may be insignificant compared to most renovation costs, but for us in our first home, this was back breaking. We continued with Suj since we were already locked in and well past the 3 day cancellation period. Their work for the most part was exceptional. The new wall blended perfectly into our existing structure, and the ceiling patch was also well done. The problem here was the floor. They had dug up a 1” deep pit in the floor, likely to remove the wall studs. However, they did not patch the floor or even let us know this was going to be an issue. We were never told about the pit until I decided to check in on their progress one day towards the end of the wall build. This required us to pay a handyman to come in next day on a weekend to patch the concrete since we had cabinets being installed the following Tuesday. Suj was aware of this and did not believe it pertinent information. Overall, Suj and SoCal Builders do quality work, but the issues in pricing consistency lost us before the work even started. Not even telling us that we’d be left with a 1” deep pit in our floor after was another huge issue which should’ve been brought up much earlier. This was our first experience with a contractor and I’m not sure if this is typical or not. However, it’s enough to make me doubt I’d contact them for any future work."
Completely renovating both the guest and master bathrooms. In the master bathroom, we're installing a spacious walk-in shower featuring dual black-finished shower heads, elegant floating benches, and marble wall tiles. Meanwhile, the guest bathroom will have a sleek built-in tub and stylish hexagon tiles.
This project involved adding a new master bathroom to the existing house. The shower features sleek white subway tiles complemented by striking black fixtures and shower door hardware. The bathroom floor is adorned with elegant white marble tiles, providing a seamless and luxurious finish. A white shaker vanity topped with a white marble countertop completes the space, creating a clean and sophisticated look.

"We hired Ben to remodel our living room and kitchen, which included adding approximately 300 square feet, creating an open floor plan, and removing an enormous brick fireplace in the center of our house. From day one, Ben was amazing to work with. He was on budget, on schedule, professional throughout the entire project, and consistently anticipated potential issues before they became problems. His wealth of experience was incredibly valuable when it came to making decisions along the way, and he was always willing to offer thoughtful advice and guidance. His entire team was fantastic as well: professional, respectful, and clearly committed to doing quality work. We couldn’t be happier with the results and our experience working with Ben. We highly recommend Ben for any remodeling, building, or construction project!"

FAQs for addition to existing structure building service projects in El Segundo, 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.
