"Saul poured a sidewalk and while the concrete work is good they left it unfinished. I have two holes now that need to be closed and cannot reach Saul, the owner. I also hired him to repair existing sprinklers and he left it unfinished. I paid him for services with the understanding that he would come after the weekend to finish the job and he hasn't been back. That was a month ago. Or close to it. I've called and texted him. He says he will come then doesn't. Never calls to explain why. Or when he'll be back."

We will make sure we bring you creative solutions done perfectly right with the help of our experts. Let's talk today! -Building with Vision.

"We received quotes from 3 different contractors. We chose GAXL because it's close to Newark and I like how Jose explains everything in detail. Originally we thought the remodeling would take 4 weeks but it took close 6 weeks. The whole project was great, the craftsmanship was superb. At one point, we found some tiles that are not very nice (from the manufacturer) and we asked them to redo the bathroom wall. They don't complain and understand our request. The workers are great, especially Marvin and this other guy (forgot his name). They WORK very very hard from 8a to 6p everyday. Jose is on time and is very prompt in returning calls or text. In fact he's the only contractor who's very prompt and I like that! On one of the walls they discovered a mold due to rain leaking and they're able to fix it in 4 days which is great. Jose and his son pickup the materials from the suppliers and drop them in our house. Overall, Jose and his men are courteous. I will definitely use GAXL for future remodeling."

FAQs for second story addition building service projects in Brentwood, CA

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
