I still remember the first real job I quoted over in Bloomfield, back when Alan Construction was mostly me, a measuring tape, and a van that always smelled like sawdust. The homeowner had already been burned twice. Two earlier crews cracked her century-old plaster, left a draft she could feel from across the living room, and vanished long before the work ever felt finished. She did not want another sales pitch. She wanted straight answers, and that single afternoon taught me exactly which questions a homeowner ought to be asking before anyone touches their house.

What I Wish Every Homeowner Asked First

The biggest mistake I see is treating this like a price-only decision. A low number on paper means very little if the crew rushes the install or skips the prep that actually makes a window last. When you sit down with a window contractor, start with the basics: their license, their insurance, and how long they have worked in this region specifically. Pittsburgh weather is hard on seals, sashes, and frames, freezing and thawing over and over through the winter. A crew that learned the trade in a mild climate tends to figure that out the expensive way, on your house. Ask for references from jobs that are at least a few years old, because a good install proves itself over time, not on day one.

Questions to Ask a Window Contractor in Pittsburgh About Older Homes

So many of our homes were built before 1940, with hand-laid brick, lath-and-plaster walls, and openings that are almost never perfectly square. That history is part of the charm, and it also makes window replacement trickier than the glossy brochures like to admit. Ask any candidate what real experience they have with houses from your era. If they cannot tell you how they deal with crumbling plaster, settled framing, or old weight-pocket sash windows, that hesitation tells you plenty. The right answer is calm and specific, not a shrug.

Historic Districts and Matching the Original Look

Some neighborhoods, including parts of the Mexican War Streets and Deutschtown, fall under historic guidelines that limit what you are allowed to install. A contractor worth hiring will already know this and bring it up before you do. Ask whether your block carries any design rules, and whether they will help you stay compliant instead of leaving you to sort it out alone.

Permits, Disposal, and the Details People Forget

Here is something that surprises almost everyone. In Pennsylvania, a straight swap that keeps the same size and location usually does not require a permit, but the moment you enlarge an opening or alter the structure, a permit is required. So ask your contractor plainly whether your project needs one, and whether they pull the paperwork or quietly leave it on your plate. While you are at it, confirm that haul-away and disposal of the old units are written into the quote. Surprise glass and debris fees are a classic trick for making a cheap estimate balloon after the work is done.

How Long Does It Take to Remove an Old Window and Install a New One?

This question comes up in nearly every consultation, and the honest answer is faster than most folks expect. A single standard unit usually takes a trained two-person crew about thirty to sixty minutes, from pulling the old one to sealing the new. Larger bay or picture windows run longer, often ninety minutes or more, because they are heavy and the fitment has to be precise. If we open things up and find rot or water damage hiding behind the old frame, we stop and repair it first. That adds a little time, and it spares you a far bigger and costlier problem down the road.

Can New Windows Be Installed in a Day?

In most cases, yes. An experienced crew can comfortably handle eight to fifteen units in a single workday, so plenty of homes are finished start to finish before dinner. The part that really stretches the timeline is manufacturing. Custom orders commonly take four to eight weeks to arrive, sometimes longer for unusual shapes or specialty glass, so the factory sets the pace, not the install. Ask for a realistic lead time at the start, and be wary of anyone promising the whole job overnight.

Warranty Questions to Ask a Window Contractor in Pittsburgh

A manufacturer warranty covers the glass and the frame, but it will do nothing for you if the labor was sloppy. So always ask about the workmanship warranty, meaning the coverage on the actual installation, and get the length of it in writing. This is also where certification matters more than people tend to realize, and if you want the full breakdown I would read Are Certified Window Installers Worth the Extra Cost? before you commit. A solid window replacement should arrive with both protections in place, not just the one printed on the manufacturer’s box. Coverage that lives only in a salesperson’s promise is worth exactly nothing.

Who Actually Shows Up on Install Day

You would be amazed how often the friendly person who sells the job is not the person who installs it. Some outfits sell the work, then hand it off to whichever subcontractor happens to be free that week. Ask your window contractor directly whether their own employees do the installing, and whether those installers are certified and trained. At Alan Construction, the crew that measures your home is the same crew that finishes it. I am convinced that continuity is half the reason our work holds up the way it does.

A Simple Checklist Before You Sign Anything

Bring this short list with you to any consultation. The answers, and how comfortably they come, will tell you almost everything about who you are dealing with.

One last piece of advice before you choose. Take ten minutes to understand how energy ratings work, because the right glass for our climate makes a real difference on those January heating bills. The government’s ENERGY STAR windows guide is a plain, no-nonsense place to start. Ask good questions, trust the contractor who answers them without dodging or rushing you, and your new windows should serve you well for decades. If you would like a straight, pressure-free conversation about your home, my door is always open.
