"I was nearly impossible to find someone willing to replace our exterior doors; Tony was the only contractor to follow through. I appreciate his responsiveness; he showed up the next day for an assessment, and his quote followed right after. He was responsive up until the install date and his work was fast and exceptional. Very happy with the work and enjoyed working with him. Highly recommend!"

"Evolution Painting did a superb job on my house! I give them 10 stars! From start to finish, they were professional, reassuring of the extra work that needed to be done, cleaned up above and beyond, and the exterior paint job was glorious. Here is a quick rundown of their excellent work: - Douglass showed up on time and sent me the estimate the next day. - He amended the estimate per our discussions and immediately sent a new quote. - They showed up on time and in positive spirits. - They power-washed and covered all items appropriately. - They prepped and removed items I could not remove and replaced them afterward. - We ran into a big hiccup with extensive rot in the corner of my house. They demolished it, removed the rotten wood, cleaned the area, reframed the corner, and put in new siding, insulation, and exterior shingles outside and inside the room, not only inside the corner but two adjoining walls and ceiling. It looks like a new house. - They removed all the trash and took away this old AC that was built into the wall by a previous owner that caused much of the rot. - They painted the shutters, doors, and handrails down the front steps. - They were kind, professional, and highly skilled. The exterior paint looks fantastic. I could not say enough about Douglas, Fabricio, and their team!"

"The company did a great job preparing and painting my deck. I thought I needed to replace the deck steps and they told me that was unnecessary because the step integrity was fine. They were enthusiastic about their work, on time, and wanted to be sure I was happy with the result. I will use the company again."

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"Mass Garage Door came within two hours. (Another firm called back after two days.) He fixed the problem quickly and inexpensively. Notably, he did not try to upsell me. This was a sharp contrast with Morris Doors, which in 2016 told me I needed to replace, very expensively, the big springs and the door itself. My garage door has worked just fine without the Morris Door repairs. In contrast Mass Garage Doors is honest, punctual and fairly priced."

FAQs for doors (interior) installation and replacement projects in Chelmsford, MA

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.
