We have been in the construction industry for over 10 years. From building ADUs, high-end kitchen remodels, bathroom remodels and home extensions, we have done just about everything under general construction. Our company prioritizes safety, quality and transparency.

"Me and my wife decided recently to get our kitchen remolded. After some time searching for the right guys to do the job we settled on RG Construction. Richard, who is the owner, is a great guy and super informative. He never left any question unanswered or left us uncertain about anything. His crew works quick, and they pay attention to the tiniest detail. They absolutely are worth every dollar and I would recommend RG Construction to any homeowner, and I for sure will be giving them a call back for any work I need done in the future. Me and my wife are absolutely in love with our remodel."

The company did not replace him, so the 1 man had to work alone, slowing down the completion of the project. Art and Johnny were great to work with. Communication with the office was a little lacking, but overall we are happy with the work."

One of the first houses I remodeled was about 30 years old. Later I remodeled one that was 100 years old. Surprisingly, they needed about the same amount of work because the older house had been built to such a higher level of quality. When I take on a project, my goal is for it to be like that 100 year old house. I want it to serve it's people well, and one day, perhaps 100 years from now, when the time comes to make a change or an update, the person taking apart my work says "wow, this was really well done and lasted a lifetime." I first learned by working on my home, then rentals. Now, my partner, Parker, and I team up to do work for others. I'll walk through exactly what you're thinking, explain what it will take and how the work will be done, and keep you updated until it's finished and you love the result. Services include... Electrical: - Troubleshooting switches, outlets, fixtures, etc. - Installing or removing switches, lights, fans, etc. - Replacing and upgrading fixtures and switches Esthetics: - Wall Patching - Painting - Curtain install - Picture hanging - Trim / Crown Molding / Baseboard install and repair Plumbing - Garbage disposal installation or replacement - Sink installation or replacement Tiling: - Tiling - Tile repair - Regrouting & More: - Garage door insulation I'm currently working on my contractor license, but please note that I don't have it yet.

Basement Remodel questions, answered by experts

If you’re not sure which method of raising the ceiling is best for you, here are a couple of considerations to help you make that decision. A professional ceiling company will be able to help you determine the best option for your home.

  • How long you are planning to live there: although raising the basement ceiling will increase the value of your home, if you’re planning to sell the house, then go for raising the house.

  • The condition of the foundation: to lower the floors, your foundation has to be intact whereas raising the house will allow you to restore the damaged foundation.

It costs an average of $32,000 to finish a basement, and most projects total between $15,000 and $75,000. If you just want to make the space look a bit nicer and don’t need to convert the basement to legal living space, you could spend as little as $3,000 to install drywall and flooring. On the other end of the spectrum, your costs could rise to $100,000 if you want to make structural changes to the space, repair existing structural damage, waterproof your basement, or install a kitchen and bathroom along with living space.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Yes, you’ll use a macerator pump to install a basement bathroom without breaking concrete. The purpose of breaking into concrete is to connect the drain pipes to the main sewer line. But a macerator pump will bypass this step and break up solids until they are soft enough to pass through a discharge pipe. That pipe will carry the waste to the sewage line.
