Upgrade Exterior Doors for Security and Curb Appeal
Door services based in Bethlehem, serving surrounding areas in NJ and PA for homes with worn entry doors, drafty thresholds, or outdated patio door systems

What Professional Door Installation Includes
You will receive a prehung door system with an insulated core, multipoint locking hardware, and a weatherstripped frame that seals against air infiltration. BNL Home Improvements removes the old unit, checks the subfloor and framing for damage, and installs the new door with shims placed at hinge points and along the strike side to prevent sagging. Thresholds are adjusted so the sweep makes contact without dragging.
What You'll Notice When It's Complete
After installation, you will notice the door closes smoothly, locks securely, and eliminates the draft you felt along the floor. Rooms near the entry will hold temperature better, and outside noise will be reduced. Patio doors will glide on new rollers and lock at multiple points, and custom entry doors will add visual weight and detail to the front facade.
The work includes door and frame installation, hardware mounting, threshold adjustment, and weatherstripping. It does not include painting, staining, or exterior trim carpentry beyond standard casing, though those services can be coordinated if needed.
Common Questions About Door Replacement
Homeowners in Bethlehem and neighboring communities often ask about materials, security features, and how new doors fit with remodeling plans.
What door material works best for exterior use?
Fiberglass resists denting, does not warp with moisture, and can be finished to look like wood. Steel offers the highest security and insulation value but can dent and needs a factory finish to prevent rust.
How does a multipoint lock improve security?
The system engages the frame at the top, middle, and bottom when you turn the handle, distributing force across the door and making it much harder to kick in. Single-point deadbolts only secure the door at one height.
When should patio doors be replaced instead of repaired?
If the frame is bent, the glass seal has failed, or the rollers are worn beyond adjustment, replacement is more cost-effective than ongoing repairs. New patio doors also offer better insulation and larger glass areas.
Why does threshold adjustment matter?
An adjustable threshold lets you raise or lower the seal to match settling or changes in flooring. This keeps drafts out and prevents water from entering during rain.
How do custom doors fit with remodeling projects?
Custom entry doors are ordered during the planning phase so the rough opening can be framed to match. This allows for wider units, sidelights, or transoms that change the scale and style of the entrance.
