"Prompt, reasonable and professional. Good crew. Came up with great ideas on other projects I have in mind. Love my new ceiling, they fixed all the rot in my subfloors and prepped for new flooring. Would recommend for all your weekend projects. Did I mention they work efficiently? what they got done in a weekend probably would have taken a 4 man crew a week. Nick, Gerry and Frank are the crew for you."

"In summary I have to say Richard was  excellent!  He came when he said he would and finished the work when he said it would be finished.  As I solicited multiple bids for the work NE Renovations was among the most competitive.  As the work was completed I was so pleased I ended requesting he come back to do additional jobs.  He was very accomadating and even explained various options on how best to accomplish the additional work.

Install Stair Railings FAQs, answered by experts

The best finish for wood stairs is polyurethane, specifically a high-durability option like oil-based or water-based polyurethane. Oil-based polyurethane provides a rich, amber tone that enhances the wood’s natural grain and is highly durable, making it ideal for areas with heavy foot traffic. Water-based polyurethane, while slightly less durable, dries faster, has less odor, and maintains the wood’s natural color without yellowing over time.

If the stairs are already covered in carpet, you will need to remove the old carpet and possibly the carpet pad. Any damage to the stairs like cracks, loose boards, or creaky treads may also need to be repaired. You may also want to sand and refinish or paint wood stairs before installing a carpet runner.

A new and safe attic ladder transforms the experience of moving between the attic and the main living space, facilitating regular use of the attic for different purposes. By carefully choosing an appropriate attic ladder, the risk of neglecting the attic and its stored items can be minimized, ensuring that the space remains functional and accessible.

Spiral staircases can be installed outdoors using weather-resistant materials, such as galvanized steel, aluminum, or treated wood. Outdoor installations may require additional coatings or finishes to prevent rust and decay, and costs may be higher due to site prep and exposure to the elements. Outdoor staircases must also comply with local building codes, which can affect the dimensions, handrail requirements, and load capacities to guarantee safety in all weather conditions.

Key signs that a railing or staircase needs replacement relate to instability, visible damage, and component failure. Check for any wobbling, creaking, or looseness when you apply weight. Visually inspect for cracks, splits, and damaged or missing balusters or spindles. For exterior deck railings, also look for specific signs of weather damage like visible rot, warping, and rusted hardware. Additionally, any railing that is outdated and does not meet current building codes should be replaced to ensure safety and prevent falls.
