Before you sign

How to hire a window replacement company in Raleigh

1

Compare the U-factor and SHGC ratings, not just 'energy efficient' claims.

2

Ask whether it is a full-frame or insert (pocket) replacement, and why.

3

Get the frame warranty, glass seal warranty and labor warranty in writing.

4

Be wary of high-pressure sales with 'today only' pricing.

Good to know

Window Replacement Company questions, answered

How long do replacement windows last?

Quality vinyl or fiberglass windows last 20 to 30 years. Seal failure (fogging) is the usual end of life.

Vinyl, fiberglass or wood?

Vinyl is the value choice. Fiberglass is stronger and holds paint. Wood looks best inside but needs more care outside.

How long does installation take?

A crew can often replace 8 to 12 windows in a day with insert replacements. Full-frame jobs take longer.
