"Pristine Construction just completed a kitchen remodel for us this December. The project was finished on time even though additional projects were added along the way. Everybody from Pristine Construction did their job in the most professional and honest way possible. Through Angie’s List reviews, I came to know their reputation. And these reviews helped me to contact Pristine. The reviews were written in a way that I saw and experienced personally the good things about Pristine Construction. My wife and I were impressed from the start. Nathan and Mike listened to our needs and tried their very best to fulfill them. In my opinion, the crews and staff are the best in their field of expertise. Throughout the project, not only our 1950s-built house had kitchen upgrade, but also had other upgrades done. These other upgrades were done without sacrificing the timeline of the project. My family are all thrilled with the result of the project. I am proud and right in choosing Pristine Construction. I will choose them again on my next home improvement projects."

"Working with Nathan & KN Remodeling was the best decision we made when undertaking our garage conversion job. Nathan understood exactly what we wanted, knew our budget parameters and provided us with a range of options that helped us stay within what we were seeking to spend. We wanted it to be NICE, but didn't need to over-do any of the finishes and spend needlessly on areas that were going to be used in-frequently. The end result was fantastic. The workmanship was of the highest order, the job was executed efficiently and with constant communication and oversight. The whole job was stress free and delivered on time. I can't recommend KN Remodeling highly enough!"

"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.

"I needed a new house built on a complex foundation. Construction Masters did an amazing job from start to finish. Mickey and Moshe listened to everything I was looking for and worked with my vision to turn it into a reality. Their attention to sight lines and details are excellent. Mickey took me through all the work of choosing lights, cabinets, fixtures, etc. The two of them work so well together! Mickey and Moshe were there every day of the week to provide oversight on the project. The philosophy of the company is one of excellence and honesty. I do not know this because it is on a website or brochure; I know it because I had the pleasure of being their client. If they create anything, from a stair banister to a luxury bath or a whole house, it will be done to the highest standards. The work they did building the whole house was so superb that when they finished, I asked to be their client again without considering any other builders. I am going to build an ADU on the other side of my property and it will be built by Construction Masters."

"The adage “You get what you pay for” rings true with MF Construction. When we were in the market for a general contractor to build our two-bedroom/two-bath ADU in San Marino, we interviewed several general contractors. Mike Maman of MF Construction was one of them. Mike showed us several of his projects as well as his own custom home. We were extremely impressed with the end results. After reviewing several competitive bids, we selected Mike because of his 40+ years of experience in building high-quality homes. During the construction of our ADU, Mike was just a text or phone call away. He kept us informed of upcoming events and visited our job site almost daily, sometimes more than once a day. He was present at all 12 of the City inspections. Every step along the way, we noted the high quality of materials Mike uses from the Ganahl lumber to the thick insulation and roofing paper to the copper pipes and shower hot mop, and mold-resistant drywall. Mike uses materials which meets or exceeds code requirements. Everyone on Mike’s team is extremely skilled in his/her craft, many having worked with him for decades. Mike is old school and does not take any shortcuts. Along with high quality construction and materials, Mike is extremely efficient. Our ADU was completed in four months, as promised. Progress was made every day. From the rough work to the finishes, Mike scheduled his team members just in time which resulted in an extremely efficient and smooth workflow. Mike builds with his heart. His passion is infectious which inspires his team members to do their best work. The results are evident in the finished product. Our neighbors and friends are extremely impressed with the quality and build of our ADU. If you value a well-built home and appreciate attention to detail, you will not be disappointed with Mike Maman. You WILL get what you pay for with MF Construction."

"Imperial Remodeling took on a top-to-bottom remodel of my small three-level townhome, including a roof-top deck. The home, which was previously occupied by a hoarder, was transformed! Gino Henn and his crew replaced everything, from the flooring in every room, to each of the 2.5 bathrooms and the leaky 2-stage roof. The roof is now an urban oasis, with turf and a deck cover. Imperial did a fantastic job. I love my totally new kitchen! Because the condo complex was old and not well maintained, there were unexpected and tricky problems with electrical and plumbing systems. But Imperial handled it all -- and stayed on schedule. The workmanship is excellent and detailed. The crew was careful and mindful of my neighbors and the cleanliness of building's common areas. Overall, I am very happy with the finished project."

"I was a little nervous and excited when starting the process for my kitchen remodeling project. Luckily after several inquires to many companies, I found the right fit. Amir was very attentive and provided great communication through the process. He would visit my home and make sure everything was running accordingly. My kitchen now looks great and very detailed. I can’t wait to host my next gathering with friends and show off my new kitchen."

FAQs for addition to existing structure building service projects in Mount-Wilson, 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.
