"This is our second project with Horizon Construction & Remodeling. They originally remodeled our primary bathroom. They did such an excellent job with that, so we brought them back to remodel our kitchen and upgrade our electrical panel. We had a good idea of what we wanted, but Mark helped walk us through our design. He made several suggestions that helped improve our design and function in the kitchen. The staff that did the work were extremely polite and professional. They cleaned up after each day of work and were overall respectful of our property. They showed up when they said they would be here. Not only does everything look great, but the quality is also wonderful! As our house was built in 1958, we did find problems with the plumbing for gas and water. We needed to replace all the lines, so we had the whole house replumbed.

"I had my kitchen redone by Mike at MF Construction about two years ago and was NOT happy with the results. I’m posting now because of a newly discovered problem. The reasons Electrical: My wife wanted a better kitchen, but all I wanted was a dedicated circuit for the microwave. The old kitchen wiring did need to be replace, (it cost us $6,800 for one room) and electrician said we needed an upgraded electric panel to 200amps at a cost of $3,800. 1. The electrician did NOT put the dedicated circuit for the microwave. Literally the only specific thing we requested of him. 2. With just a little bit of research I found we did NOT need the upgraded panel, which would have cost $3,800 PLUS almost $1,000 more to move some waterpipes away from it for code reasons. I called Mike and asked him why they said I needed one. He had the nerve to tell me that I was the customer and should know to ask more details. I told him that HE was the contractor and we hired him to help us navigate the process. As a homeowner, how am I supposed to know about electrical details? He begrudgingly took the item off the contract, and we stuck with the existing panel 3. The electrician refused to install our stove’s exhaust hood because someone in the past accused him of scratching theirs. Mike and a couple of laborers “installed it”, but the chimney, the piece that goes from the hood to the ceiling, wasn’t attached and was bent in. I fixed that myself later 4. Upon me writing my first negative review, Mike begged me to take it down and set up an appointment for the electrician to come over. I explained about the dedicated circuit and the electrician said the outlets were evenly split between two different circuits. I said I understood, but I wanted the microwave on its own because when the toaster oven was on, and you tried to use the microwave, the power drained and the microwave slowed. The electrician said, “Just run the cord to that other outlet”. I didn’t want a big black cord would be running across my new counter, I wanted a dedicated circuit. He then RAISED HIS VOICE while pointing to each outlet, “One, Two, One, Two, One, Two!” Mike stopped him and asked what it would take. They said they needed to rip out part of a wall, and would take days. Then the electrician again said, “But why, just run the cord across!”. His voice was louder this time and I demanded he leave and not yell at me in my own home. He kept arguing and I had to again ask him to leave…I was feeling unsafe at this point…but asked again, for a third time and Mike finally lead him out. As he stomped down my drive way he was yelling back at me that I was ignorant and to never call him again. This last part is all on my security cameras. Plumbing 1. We purchased an under-sink water filter and I asked him to hook it up for us. The entire installation consisted of attaching an adapter, that’s it. Anyone can do it, but since the plumber was just installing the valves, I asked if they could do it. Mike said it would be an additional $60 to $100. I was stunned. He said they would go ahead and install it and I could pay him after. I told him no, I would take care of it…I was livid. The plumber was much nicer, and said it was no problem and would only take a minute to do it and to not charge me General 1. When Mike had the crew move my fridge out, they marred the side of it. Luckily for us it was on the counter side. At the end they went to my garage to move it back in and kicked over a glass patio candle, spilling oil over the floor and shattering the glass. 2. Within a couple of weeks, the paint on the cabinets cracked and the doors didn’t line up. Mike did send someone out to fix that. NEW PROBLEM Today, September 15, 2022, I found a new issue. I tried to turn off the water to my sink and the valve isn’t working. After less than two years I am now forced to hire a plumber to come in an replace it with a quality one. How bad does a valve have to be to fail so quickly? After getting the cabinets fixed, and having Mike tell me he was sorry and because of some medical issues he let the quality suffer, I had forgiven MF Construction, despite the ongoing electric annoyances, and took down the bad review. After this new issue popped up again, it all came back. AVOID THIS COMPANY. There are many great GCs out there, so don’t take the chance. Additionally, as shown in the photos, the finishes were pathetic, as well. I ended up doing painting touch ups myself."

Sunroom or patio enclosure building services FAQs

A sunroom delivers exceptional benefits by enhancing your home’s value and quality of life. It offers a 49% return on investment by adding versatile living and entertainment space, while its design incorporates abundant natural light and climate-controlled comfort. This additional room not only provides a welcoming area for relaxation and social gatherings but also serves as an ideal setting for indoor gardening, thereby creating a harmonious blend of indoor and outdoor living.

Yes, you can build a sunroom in any climate when it’s engineered with good insulation and quality materials. A four-season sunroom retains warmth effectively in cold weather while offering an inviting, light-filled space throughout the year. Superior insulation and precise construction methods ensure that even in severe climates, the sunroom remains safe, comfortable, and energy-efficient, making it a sound addition to your home.

A standard sunroom project takes four to six days to complete, while more complex builds take two weeks to complete. The project duration is driven by the scope of work and the efficiency of the professional crew. Comprehensive planning, precise material preparation, and dedicated installation all contribute to a well-managed timeline that ensures your sunroom is completed without unnecessary delays.

When choosing between a sunroom and a room addition, the decision must be guided by how you want to transform your living space. A conventional room addition, such as a 12-by-12-foot extension, costs from $11,520 to $28,800, while a sunroom is priced from $22,000 to $43,000 and offers a dedicated area that harnesses natural light. The sunroom provides an elegant space for relaxation and entertainment, but a room addition increases usable interior space in a more traditional manner. Engaging a skilled contractor will ensure that either option meets your specific functional and aesthetic requirements.
