"Abraham and his team were awesome. They help us remodel our kitchen and bathroom, and did a great job. We met with several companies before starting our project, but decided to go with My Construction Group because of the great communication and clear cost structure. Abraham really went above and beyond for us! I would highly recommend them to my family and friends."

"Karol is very nice and easy to work with. He pays attention to details and will actually go to the site to check the condition of my front porch. He would also call me to discuss the repairing options and materials which we could use to save us money. He charges a reasonable price for a good quality job. We are quite happy with our front porch's new look. I would highly recommend Herman Construction as they are reliable and trustworthy. We will definitely come back to Karol again if we need help in the future."

"Choosing the right contractor can make or break a home project—especially when it involves major remodeling, new structure, interiors, and utilities. As first-timers, we wanted someone we could trust, and All Weather Construction (AWC) exceeded our expectations. Recommended by a friend, they stood out for their honesty, communication, and craftsmanship. From our first call, Long gave us a clear picture of budget, timeline, and possible challenges. He helped us get ahead of permit delays, guided smart design choices, and maintained exceptional attention to detail throughout. We completed the project on schedule and only slightly over budget, mainly due to upgrades we added. Long can be hard to reach at times since he manages multiple projects, but he always follows up promptly and thoughtfully. We’re thrilled with the results and highly recommend AWC for any renovation or new build. "

"Ofer and the team firstly started VERY QUICKLY - he said he would start in a couple of days and he did. Demolition was quick and easy for the team. Throughout the 5 month project (which is fast for the amount of work we did) we had a number of things change because our plan had to change given structural limitations but Ofer and the team were always willing to think through options and work with us on the best solution."

"I debated leaving a review for the past two years as Avi, the general contractor, was a nice guy and I believe means well, but in since the remodel of two bathrooms and a kitchen, quite a bit of the work from his company has proven to either fall apart, be of poor workmanship, or simply be installed or built incorrectly. There are so many things that were done wrong, it would take forever to list, so I will mention the top few. I have plenty of pictures to illustrate the details but am not being given the link to upload them on here, for some reason I found Bay Remodeling Kitchen and Bath by reading several online reviews and when I called the company, the owner, Avi, did arrive at my home promptly and gave a very professional presentation complete with previous work, which seemed of high quality. I felt immediately comfortable entrusting him with the remodel of ONE bathrooms and a kitchen of a home I recently purchased as my primary residence. I was excited as my son had just been born and the house was to be our ‘forever home’. Day 1: I went to the house to find his demolition crew was busy demolishing....the wrong bathroom. They had gotten so far into the work it was past the point of ‘no return’. To his credit, Avi did immediately contact me and apologize. Because that bathroom was intended to EVENTUALLY be remodeled, we worked out a fair price to include it in the overall remodel. Problem solved? Unfortunately, no. Weeks on: Both bathrooms were completed and I was happy with the result. Then the kitchen. Demolition went smoothly, new wiring, plumbing and flooring were installed and the cabinets were next. I drove to the house to find....the brand new refrigerator had been STOLEN. I called Avi, who was out of town, then the police to file a report. When Avi’s foreman showed up, he expressed his suspicion the cabinet installers may have stolen it. I didn’t point fingers and patiently waited for the police to complete their investigation. Nothing came of it as it was a ‘...his word against theirs’ type of situation. I ultimately filed an insurance claim, paid the deductible and moved on. Admittedly, there is no way I can prove Avi’s guys had anything to do with it. Two days later: cabinets installed and most of the hardware had been drilled into brand new drawers and doors crooked. Pictures included with a level for reference. I was met with immediate resistance from Avi and his foreman stating, ‘...it isn’t that bad...’. Maybe not. The readers on this review can decide.After completion: 3 electrical outlets on the walls opposite the kitchen are without power. Avi shows up with his foreman and their response: ‘...we don’t even know these outlets ever had power even before the remodel...’. True, but what are the odds? Two years on: I finally notice the stoppers for the all of the drains in the bathrooms were never installed. I rarely use the bathroom sinks for more than brushing my teeth, so I don’t need to fill a sink with water but my wife recently discovered this when washing something. As a coincidence, I recently found these tucked in a corner of the garage. If the actual pop-up drains are still in boxes, I have no idea what is actually installed in the sinks. Little details I recently noticed: the ‘hot’ and ‘cold’ water positions on all the kitchen sinks are inconsistent, cabinet doors are uneven, floor moulding in more concealed locations never installed, etches can be seen in the ceiling where recess lighting had been misaligned, leaving the initial partial cuts in the ceiling in view. These problems were brought up later to Avi but at the time he was still searching for a construction team to work with as he apparently moves from one team to the next. Reading these reviews, I see he occasionally finds a good crew to work with, but a note to future customers: Avi and many general contractors subcontract with myriad plumbers, electricians, tile workers, etc. If he has a few bad subcontractors, you result might be similar. Good workers will likely produce a good result. Buyer beware... Updated 5/17/24 Addendum: Avi recently reached out regarding the quality of the previous project and said he now has a good, reliable, meticulous crew that he trusts. I took the risk, but let them back into the house. They were, indeed, a good, quality crew and fixed the as many of the mistakes and shortcuts the previous crew made and took. I am very happy with the outcome. As my earlier review stated, Avi is a good, honest guy but the quality of the work being done will 100% depend on the crew hired. Thank you for following up, Avi. -Chris"

"It's difficult to trust contractors these days. We had a bad experience in the past with another contractor and we were very hesitant to use one again. However, we decided to give Tech Line Construction a chance because our friend recommended them. We are so glad that we did! They painted the exterior of our house and handled a bigger project for our property. I admire how Luis always kept us in the loop and he was always available to answer our questions. We'll pass the word to our friends and family about this company. They're the real deal!"

"It went well. There were some surprises. Damaged shingles and structural damage were discovered once we were underway. This lengthened the duration and cost of the project. Fortunately Sigura has carpentry capabilities in addition to their painting skills and were able to make the needed repairs before resuming the painting. The rest went without a hitch."

"Hired Benlo for a partial home renovation including some structural walls. It's hard to find contractors who actually manage the project from start to finish without disappearing, but Benjamin was on-site frequently and kept the crew on track. They were very clear about the costs upfront and didn't hit us with 'hidden fees' halfway through. Very satisfied with the professional approach."

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