Door Installation in Chicago
Seamless Fits. Secure Installs. Lasting Quality
Door Installation, Done Right
Great door Installation start with great installation. At Costello Carpentry, we make sure your new door looks sharp, seals tight, and operates smoothly from day one. From statement-making front entries to quiet, well‑fitting interior doors, our team levels, shims, and seals every unit to manufacturer specs for long‑term performance. We install pre‑hung and slab doors in solid wood, fiberglass, and steel, and always finish the job with crisp casings and hardware that feels solid every time you close it.
Need more than a basic hang? We handle tricky openings, out-of-plumb walls, and historic frames, repair or replace damaged jambs, and match existing trim profiles so the new door blends in cleanly. You get clear pricing, lead times that stick, and a crew that protects floors, hauls away debris, and leaves the space cleaner than we found it. We’re licensed and insured, prep for Chicago weather on exterior units, and can add smart locks, peepholes, closers, and privacy kits on the same visit.

Frequently Asked Questions
How long does a typical door install take?
Most interior installs take about 60 to 90 minutes per door. Exterior units take 2 to 4 hours because we set sill pans or flashing, adjust thresholds, and tune weatherstripping for a tight seal.
Do you supply doors or install customer supplied products?
Both. We can source solid wood, fiberglass, and steel doors that match your budget and lead time, or install a door you already purchased. Share measurements and a quick photo of the opening so we can confirm fit.
How do you prep for Chicago weather on exterior doors?
We install a sill pan or flashing, insulate gaps with low expansion foam or mineral wool, use backer rod and high grade sealant at critical joints, and set thresholds and weatherstripping for even compression.
Can you add hardware and smart locks?
Yes. We prep and install deadbolts, smart locks, peepholes, closers, and privacy kits. Hinges and strikes are aligned so the door closes smoothly without rubbing or rattling.
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 you have an alarm contact on the door, let us know so we can plan a clean transfer.
What warranty do you provide?
Workmanship is covered for one year. Manufacturer warranties for doors and hardware remain in place, and we document install details for future claims.
