"We've had a great experience with Precision Door and Window. So far they've replaced our gutters, a back door, and we're about to go under contract for our roof. Prices are very fair and reasonable (we got multiple quotes). They are very communicative, show up when they say will, and are just overall nice people. Also, the work they did was great. Highly recommend them."

"The doors on a new piece of furniture hung uneven and was very noticeable with the hardware. Torin was able to work magic and re hang the doors to make them all level! He also replaced the outdated hardware with new modern handles. I?m very happy and has improved the overall look of the room. Will absolutely work with Torin again on future projects."

"I had my existing wood cabinets restrained. I did not want them replaced or refaced which most companies want to do and they did exactly what I wanted and in a timely fashion. The workers that performed the work were friendly and professional and my cabinets look great. Thank you Amie, Mike and ,Pedro"

Customers say: Quality work

"This is the 2nd job we has Steve do for us. The was a min bathroom renovation and also kitchen backsplash. Bathroom came out great. He walled off a second door to access the bathroom, ripped out old tile, and put down new tile and installed a new vanity. Very happy with the finished product. Steve also did the backsplash in the kitchen. It came out perfect. I would definitely recommend Steve for any home improvement projects you may have."

"I was looking to have an in law second floor kitchen done, and had been searching for awhile for a contractor to do the cabinet installation and then I found Jim Longden . I challenge anyone to find a contractor better than Jim Longden. He responded quickly to do an estimate, was professional, personable, and did a great job in a short amount of time for a price that was very affordable. Jim told me he could do it in one day, and it took him one day. He gave me an affordable price, and stuck to that price. He was clean in his workspace, no mess, and was respectful of the existing structure, like the hard wood floor. If you want something done right, for a great price, and in a timely manner, you'd be hard pressed to find someone better than Jim."

FAQs for doors (interior) installation and replacement projects in Nashua, NH

If your existing frame is in good shape, you can replace an interior door without changing the frame. This is a budget-friendly option because it saves on the cost of removing and installing a new frame. By choosing a slab door that fits your current frame, you'll save on labor and materials. Just make sure the new door matches the old one's dimensions for a smooth replacement.

Standard interior doors are 80 inches tall and range from 28 to 32 inches wide. Interior doors vary from 24 to 36 inches wide, depending on their purpose and the available space. Building codes require interior doors to be at least 80 inches tall and 24 inches wide. Knowing standard sizes helps you select a new door that fits properly in your existing opening.

It costs $600 to $2,000 or more to move an inside door. The total price depends on your location, the type of door, and materials needed to complete the project. Moving an interior door requires walling up the leftover space and opening up a new wall where you want the door to go instead. You’ll also want to plan for the expense of framing the new wall opening and adding trim.

Exterior door installation costs an average of $1,175, with a typical range of $525 to $1,800. The higher expense compared to the cost of interior doors comes from the need for exterior doors to be weather-proofed and they are often made of thicker, more durable materials. The associated exterior hardware must also be able to withstand harsh weather, so these cost more as well.

It costs between $300 to $2,500 to make a doorway wider on average. However, the wider you need the space to be, the more it will cost. Some homeowners choose to widen interior doorways to make the house more wheelchair accessible. In order to be wheelchair accessible, an interior door needs to be at least 32 to 36 inches wide. Also, some older homes just have narrow doorways due to the nature of how homes were built differently many decades ago.

It takes between two to five hours for a professional door installer to install an interior door, depending on complexity and materials. A pre-hung door typically takes around two hours, and larger doors like double French doors can take up to five hours. If you’re doing the project yourself, expect it to take a little longer than that, especially if you have little to no experience completing this type of project. Keep in mind that a pre-hung door can be installed about an hour or two faster than a slab door.
