  I recently remodeled my house and was sorely disappointed. I was a bit gun shy to try again, but changed my mind after being stuck ay home during the covid lockdown. I decided to find a new contractor, and was lucky enough to find Mark Besnos, the owner of Horizon Construction and Remodeling. Mark was able to make my vision a reality, which was no small task. He worked with my designer, Misti Riedel and I and had the patience of a saint. This time around, it was an enjoyable experience. I wake up every morning and walk out into the main living area with a big smile on my face. Before Mark remodeled, my place was so drab. I truly love my house and thank everyone for helping me

  5.0

  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

  This review for Regal Construction is overdue but I can recommend this company with more confidence now since I have never seen a construction company (or any companies) stands by their work beyond the scope of the agreement. My husband and I have experienced six contractors since 1998 for remodeling and landscaping of our homes. Being matched with a reliable, competent and civilized contractor seems to require more than online research; Rather, you need a luck equivalent to the chance of jackpot in Vegas. For our current home, we planned the remodeling of the entire downstairs which included kitchen, family room, living room, powder room, laundry room, gym and bathroom. After interviewing several contractors very, very carefully (since we had a contractor from **** in 2016), we decided to work with The Regal; Sean and Shaul. They were very precise with the budget and timeline while explaining each phase of work in detail; nothing too extravagant or too cheap to achieve. We started in March 2020 and finished the project by June as they promised. Most importantly within the budget and timeline plus some extra improvement of the house thanks to their recommendation that eventually saved us a lot of energy and money. I am not saying that the entire experience was as smooth and rosy as it may sound like; There were some moments of tension and questions on the way like any remodeling projects would create. But all within my realistic expectations and any issues were quickly resolved with the sincerity and efforts of Sean and Shaul. They are such civilized professionals that communication was the best part of the whole project (very rare in the field of construction). My husband and I are professionals so dealing with people who are deceiving or irrational has been the most challenging task along with our aging brains. The project manager Shaul was a god sent and he made the whole experience quite comfortable and sane. Also, all their workers were polite, clean and hard-working (again very rare). I have waited to write a review more than two years because I wanted to see how their warranty service would work out. It was beyond my picky expectations! They are highly responsible for their job and extremely prompt, sincere and efficient with any issues related to their work (they don't seem to care about expenses to make sure all is in a great working condition). We are done with our home renovation but we will definitely recommend The Regal to our children or friends with great confidence. It was a good match after all! :

  RKM is a great company. We have used them since 2016 when they installed our heating and air conditioning system. We have them maintain the system twice a year. They are always reliable. The system works great and we've never had a problem. Even on the hottest days of the year, we have great AC. We highly recommend them

  Mark was fantastic! Middle of a heat wave my 9 month pregnant wife and I lost our AC. We called Mark the next morning and he was here three hours later. He worked tirelessly to diagnose the problem and went above and beyond to remedy the issue. Outside of the exceptional work performed he was friendly, caring, and extremely responsive to any questions or requests I had
