"They were very thorough. They went up onto the roof with an iPad and they took pictures of the whole surface of the roof and it was to show us that it was in good condition and didn't need any repairs. They came into the house and then went upstairs to the attic to see if they could see any holes from the inside and thankfully there was nothing there. What I really appreciated was they were thoughtful enough to put little bags over their shoes so they wouldn't get my carpet dirty when they came into the house. They were right on time."

"RORHI completed our basement renovation. They did fantastic work, and all the contractors were highly professional: the framers, the insulators, the drywallers, the electrician, and the finishers. They went above and beyond to accommodate some special requests, like installing a commercial dehumidifier and finishing the walls of the storage closet, which were not part of the original scope, which greatly enhanced the finished look. We had a great experience working with Evan, Mike, and Matt (the initial estimator), as well as Inmer (finishes and framing), Eddie (painter), and the electrician. Despite minor miscommunications leading to necessary changes, they promptly addressed our concerns, sending someone immediately or the following day to resolve issues. Overall, we were impressed by RORHI's dedication and responsiveness, and we plan to hire them again for our next projects."

"This may be my 3rd or 4th review, I lost track but the job results don't change. Chris and his staff are consummate professionals. He's a busy guy, so you may have to wait a while to get your work done, but he won't lie to you about time, and having the job done right the first time is well worth the wait. I can't say enough good things about his company, and highly reccomend him for any home repairs or remodels. Thank again Chris!!!"

Customers say: Quick response

"I was looking to build a pool house / storage shed for a very specific location. I contacted Mike about the project and am very happy I did. He was excellent to work with from start to finish. I had a design in mind and he worked with me to make it a reality. Working with Mike was so easy and seemless. He always returned calls or texts and was always on site when he said he would be. I couldnâ t be happier with the experience and the finished product. It turned out exactly as I had hoped from the design to quality of work. I highly recommend contacting Highland Home and Garden if youâ re considering a project. You wonâ t be disappointed"

Basement Remodel FAQs, answered by experts

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

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.

If you have the woodworking experience to build a bar from scratch and you have the time, DIYing the work is a no-brainer and can save a few thousand dollars. However, if you’re looking to include a sink, additional lighting fixtures, or high-end bar tops and cabinets, it’s usually a better idea to call in a pro. It will cost more, but the finished product will likely be worth it.
