"hired Frontier Remodeling for a home remodel, and it was a mistake. I selected them based on Aron telling me his guys were skilled, focused on quality, efficient, and clean. I experienced none of that. Work progressed slowly for 3 months. They rushed and cut corners at the end so they could finish and get paid. Quality was very poor, workers did not respect my property, and my new home was an unorganized filthy mess for 5 months. The only thing about Frontier Remodeling that was organized and punctual was Aron asking for progress payments. In the end, I had to hire other contractors to correct a fair amount of work."

"We recently completed an extensive remodel of our home—new windows, fresh exterior paint, two fully updated bathrooms, new interior doors, upgraded flooring, and a complete transformation of our primary bedroom. The results have exceeded our expectations, and we couldn’t be happier. This level of satisfaction was only possible because of the personal and professional attention from David Eskin. From our very first meeting to his final message saying, “We are done,” David was attentive, thoughtful, and full of professional recommendations we would never have considered on our own. He kept us informed at every step—through each hiccup, process, and inspection—so we always felt confident and included. What began as a plan to simply “fix the house up until we find another home” has turned into “we’re staying,” because the craftsmanship is extraordinary, and it truly feels like home. We will be using Horizon for Round 2!!!"

"Full kitchen and bathroom remodel. (Loft condo) From my initial meetings with Anar the owner, to meeting the team that did the install It was an entirely stellar experience. Anar presented me with samples and a clear understanding of the project scope. A project manager was assigned that came out to the site on a regular basis to monitor progress and quality. The two gentleman that came out to do the installation were personable..and maintained a clean workspace and professional attitude throughout. Both obviously skilled for the job duties. There was great care taken during the project on communication regarding the installations, and leaving the site as undisturbed as possible (clean) and with respect to property rules. (Condo). The fixtures and materials offered were all top quality and brands. Project oversight and city permits were all handled by the project manager. A very high level of communication and attention to detail were provided throughout the project. My spouse and I are very happy with the results, and this is added tremendously to the value of the property. This is our first remodel, and although it is an inherently stressful undertaking, Anar and his team really delivered with service and quality. ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ gentleman! Thank you again!

FAQs for sunroom or patio enclosure building service projects in Ontario, CA

A sunroom is a fully enclosed space with walls of windows or glass. It allows you to enjoy the outdoors from the comfort of the indoors, protected from bugs and weather. It functions as an additional room in your home. A covered patio extends your home's roof over an outdoor area, providing shade and shelter while remaining open to the fresh air. It's a great way to enjoy outdoor living while being protected from sun and rain.

Adding screens to your porch is the most budget-friendly way to enclose it. Screening keeps out insects and debris while letting you enjoy the breeze and outdoor ambiance. It's less expensive than installing full walls or glass enclosures and doesn't usually require permits, making it an efficient way to upgrade your porch.

If you're transforming your porch into a fully enclosed living space like a sunroom, you'll likely need a sturdy foundation, such as a reinforced concrete slab, to support the structure. For a simple screened-in porch, you might be able to use the existing floor and support posts without additional foundation work. It's best to consult a professional to determine what's needed for your project.

An enclosed porch can be considered a living space if it's fully enclosed with solid walls and windows, has a proper roof, and includes heating and cooling systems. It should also have direct access from inside your home. When these criteria are met, the space becomes an extension of your home's livable area.
