Door Installation and Repair Services

Whether you’re replacing an outdated entry door, upgrading your interior doors, or repairing everyday wear and tear, we provide dependable door services tailored to your home. Careful installation and quality workmanship deliver lasting improvements to both appearance and functionality.

Doors That Look Better and Work the Way They Should

A door should open smoothly, close securely, and complement the surrounding space. When a door sticks, lets in drafts, fails to latch, or shows signs of damage, it can affect your home’s comfort, security, and energy efficiency.

We install and repair doors with close attention to fit, alignment, hardware, and finishing details. The result is a door that looks right and performs reliably through everyday use.

Interior and Exterior Door Services

From a single repair to replacing multiple doors throughout your home, services can be tailored to fit the project.

Door installation and repair services include:

  • Front and exterior entry doors
  • Interior doors
  • Patio and French doors
  • Sliding doors
  • Closet and pantry doors
  • Door frame and trim installation
  • Hardware, hinges, handles, and locks
  • Draft and weather-sealing improvements
  • Sticking, sagging, or misaligned door repairs
  • Damaged frame and trim repairs

Professional Door Installation

Even a high-quality door can underperform when it is not installed correctly. Gaps, poor alignment, and improper sealing may lead to drafts, difficult operation, moisture intrusion, or unnecessary wear.

We carefully measure the opening, prepare the frame, align the door, install the appropriate hardware, and complete the surrounding trim. Each detail is addressed so your new door operates smoothly and fits the space as intended.

Door Repairs That Extend the Life of Your Door

A problem door does not always need to be replaced. Repairs may be able to restore its appearance and operation while helping you avoid the cost of a full replacement.

Common door problems include:

  • Doors that stick or drag
  • Loose or damaged hinges
  • Doors that will not latch
  • Drafts around exterior doors
  • Cracked or damaged trim
  • Misaligned frames
  • Worn weatherstripping
  • Damaged handles or locks

After evaluating the door, we’ll explain whether repair or replacement is the better option for your home.

Choosing the Right Door for Your Home

The right door depends on more than appearance. Location, durability, security, insulation, maintenance, and available space should all factor into the decision.

We’ll help you choose a door that fits your home’s style and meets the practical needs of the space. For exterior doors, that may mean prioritizing weather resistance and energy efficiency. For interior doors, privacy, sound control, and design may be more important.

Frequently Asked Questions

Why does my door stick during certain times of the year?
Seasonal humidity and temperature changes can cause wood doors and frames to expand or contract. A sticking door may also point to loose hinges, frame movement, or alignment issues. We can identify the cause and make the appropriate adjustment or repair.
Why won’t my door latch unless I lift or push on it?
The door or frame has likely shifted out of alignment. Loose hinges, seasonal movement, settling, or a misaligned strike plate can all cause this issue. Correcting the underlying alignment typically provides a more reliable fix than simply moving the latch hardware.
Can a drafty exterior door be fixed without replacing it?
Often, yes. Worn weatherstripping, a damaged sweep, small gaps, or improper alignment can allow outside air into your home. If the door and frame are still in good condition, sealing and adjustment may solve the problem without requiring a full replacement.
What should I prioritize when choosing a new front door?
Consider security, weather resistance, insulation, maintenance, and style—not just appearance. The right material and installation method can help reduce drafts, withstand Northern Colorado weather, and improve the overall look of your home’s entrance.
Is it possible to install a new door in the existing frame?
A new door can sometimes be fitted into an existing frame, but the opening must be square, stable, and in good condition. If the frame is damaged or significantly misaligned, a prehung door replacement may provide better performance and a cleaner finished result.
Should damaged trim be repaired when the door is replaced?
Yes, especially when the trim is cracked, loose, water-damaged, or no longer fits the new door correctly. Addressing the frame and trim during installation creates a more finished appearance and helps prevent gaps, drafts, and future deterioration.
