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."

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

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand. 

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Envision the type of bar experience you'd like to create for your guests. For example:

  • Does your basement have enough finished space for bar stools or seating?

  • What type of additional lighting would set the tone for the room?

  • Are there basement windows or an HVAC system?

  • Do you need new plumbing in your basement for a proper wet bar?

  • Could you be happy with a built-in wall cabinet bar rather than a full-scale wet bar?

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs.
