"I interviewed a few people before making my decision using Rok and Iâ m glad I did. I did a complete gut renovation and he basically made my revision come to fruition. Even with the delayed/problems with renovations he always kept me informed. U told me he would always have someone at my house working and that he did. Not like the contractors Iâ ve worked with in the past that say that but then once they get the job.. the â oh someone would be thereâ and no one comes. I had a leak issue and he made it to my house 10 pm to assure it was taken of. Roc is reliable and hard working."

In business since 1964, we are fully licensed and insured and one of the few area firms EPA lead certified. We will provide excellent recent references. We work with your architects or ours. additional website: decksofny.com. crosscountyhomeimprovement.com. We do not put together pre-purchased gazebos.

"Dave and his team were wonderful to work with. We met with several contractors for our new deck and Dave was recommended by our architect. He was extremely responsive and we found his rates were comparable to others we received. We were stalled for a while due to Covid, but once our permit was approved, Dave kicked off work for us the next week. He was very communicative, sharing updates, hiccups (fortunately not too many - usually product delays), and recommendations. I can't say enough good things about his crew. They always arrived on time and worked diligently. They also indulged the many questions my husband and I had! We've already recommended Dave to another friend and would happily use him again for future relevant work."

Basement Remodel questions, answered by experts

Home improvements that increase value not only enhance quality of life but also offer a high return on investment (ROI). Replacing a garage door has one of the best ROIs at 93%. Other high-ROI projects include remodeling your kitchen, installing a stone veneer, and replacing windows. These updates make homes more appealing to buyers and improve functionality, which helps if you plan to sell your home in the future.

Yes, you can install a summer kitchen or kitchenette in your basement. They serve similar purposes as outdoor kitchens, keeping the main floor of the house cool and providing another space to cook and congregate. Basement kitchens are also a worthwhile alternative for homeowners without much space in the backyard. They come with a few logistical questions to sort out, though, like ventilation and waterproofing.

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.
