Door fRAME REPAIR AND REPLACEMENT In Chicago
Strong frames, tight seals, clean finishes
Door Frame Repair and Replacement Done Right
A solid door starts with a solid frame. When a frame is out of square, rotted, split, or loosely anchored, you get sticking swings, drafts, rattles, and leaks that never seem to go away. We diagnose the cause and correct the frame so your door closes smoothly, seals properly, and looks like it belongs.
Costello Carpentry repairs and replaces door frames for both interior and exterior openings. We work with wood, composite, and steel-compatible jamb systems built for Chicago weather. For repairs we sister jamb sections, reset hinges with longer screws into framing, relocate strikes, and tune thresholds and weatherstripping. For replacements we set the new frame plumb, level, and square, fasten through the jambs, insulate the cavity, and finish with crisp casing that matches your trim
Quality You Can Feel, Start to Finish
Every door frame repair & replacement is done the right way, in the right order.
-
True square and reveal: We correct racking, verify the opening, and set shims so the jamb sits plumb, level, and square.
-
Solid anchoring: Frames are fastened through the jambs with proper screws into studs for long term stability, not just nails.
-
Weatherproof at the sill: Exterior units get a sill pan or flashing plus backer rod and pro sealant where it matters most.
-
Insulated and quiet: We fill gaps with low expansion foam or mineral wool to cut drafts, moisture, and street noise.
-
Hardware tuned: Hinges are set, strikes relocated if needed, and thresholds adjusted for a smooth, confident close.
Most installs wrap in one visit.
We serve Chicago neighborhoods including Logan Square, Lakeview, Lincoln Park, Wicker Park, Bucktown, Irving Park, and Jefferson Park—plus nearby suburbs like Oak Park and Evanston.

Frequently Asked Questions
How do I know if I need repair or full replacement?
Repair works when damage is localized and the wood is still sound. We can sister jamb sections, reset hinges with longer screws into framing, relocate the strike, and tune the threshold and weatherstripping. Replace the frame when there is rot at the sill or lower jambs, the opening is racked out of square, or the door still will not latch after adjustments.
How long does a typical job take?
Most frame repairs finish in 60 to 120 minutes. Full frame replacements usually take a half day to a full day depending on exterior flashing and trim complexity.
Do you supply materials or install customer supplied products?
Both. We can source paint grade or stain grade wood, composite or rot resistant jamb systems, and hardware. If you already purchased materials, send measurements and a quick photo so we can confirm fit and any extras needed.
What does weatherproofing include for Chicago conditions?
Exterior frames get a sill pan or flashing, low expansion foam or mineral wool in the cavity, backer rod and high grade sealant at critical joints, and thresholds and weatherstripping tuned for even compression to block drafts and wind driven rain.
Can you match my existing trim and finishes?
Yes. We stock common casing profiles and can source to match. We finish with crisp casing, tight miters, and clean paint lines so the work blends into your interior.
Can you repair a frame after a break in and improve security?
Yes. We replace split latch side sections, add reinforced strike plates, set longer hinge screws into framing, and can upgrade locks or install smart locks during the same visit.
Do you paint or stain the new frame?
We install primed or bare material ready for finish. Painting or staining can be included on request or coordinated with your painter.
What should I do before the crew arrives?
Clear a 6 to 8 foot area on both sides of the opening, remove nearby wall decor, and secure pets. If the door has an alarm contact, tell us so we can plan a clean transfer.
What will my estimate include?
An itemized scope that calls repair vs replacement, the materials to be used, any weatherproofing or hardware upgrades, and firm timelines. No ranges or vague allowances.
What warranty do you provide?
Workmanship is covered for one year. Manufacturer warranties on materials and hardware remain in place. We document key install details for any future claims.
Where do you work?
