"Needed to replace an old door that was weather beaten and worn out. Mark came out to check it out and was able to quote an upgrade replacement on the spot. We agreed and just a few days later they came out with the new door and installed it very professionally. Looks great, works perfectly!"

"Excellent Service with Great Attention to Detail! I recently hired TruBlue to help with some home improvement projects, including hanging pendant lights in my kitchen and mounting artwork on my walls. From start to finish, the experience was seamless and professional. The team arrived on time, worked efficiently, and completed everything in a timely manner without cutting corners. They paid close attention to detail, ensuring the pendant lights were perfectly aligned and at the right height. It made a huge difference in the look and feel of the kitchen and I was happy with their work. When it came to hanging the art, they took the time to measure and position everything precisely, making sure it was level and looked just right in the space. I appreciated their professionalism, skill, and the care they took with my home. It’s clear that TruBlue takes pride in their work, and I wouldn’t hesitate to use their services again for future projects. Highly recommend!"

FAQs for doors (interior) installation and replacement projects in Diamond Bar, CA

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.
