Manchester Window Replacement provides professional french doors in Manchester, NH for residential and commercial properties across the New Hampshire Merrimack Valley. French doors are the one product on this site where the interior and exterior versions of the same job fall under measurably different rules, and it is worth ten minutes of your time to understand which one you are buying.
An interior pair between a dining room and a study disturbs painted surface inside a room, where the federal threshold is six square feet. An exterior pair onto a deck disturbs painted surface outside, where the threshold is twenty. Same doors, same house, same crew, and a materially different scope depending on which wall they go in.
Neither threshold is as generous as it sounds once you apply the counting rule, which says the entire surface area of a removed painted component is what counts. On a house from the 1920s, a pair of doors plus their casing, head and jambs is a great deal of painted component, and interior work in particular tends to blow through six square feet at the first casing.
Interior french doors on this housing stock are frequently original and frequently worth keeping. Manchester has a lot of houses where a pair of glazed doors between the front and back parlor has survived under six coats of paint, and stripping and rehanging those is a better outcome than any replacement we could sell. It is also work with its own dust rules, which we follow.
For exterior pairs, the specification issue is the astragal and the multipoint lock. A french door has no mullion, so everything depends on the meeting stiles pulling tightly together at the top, the middle and the bottom. A single center latch on a pair of exterior doors in this climate will let daylight through the meeting stile within a few winters.
Swing direction deserves more thought than it gets. An outswing pair sheds water better and is harder to force, and it also means clearing snow off a deck before you can open your doors in February. An inswing pair eats floor space and works all winter. Neither is wrong, and whichever we recommend, we will say which trade you are making.
Sill height and the threshold detail are where these leak. A low, accessible threshold is easier to walk over and much harder to keep watertight when snow banks against it, and the pan detail underneath is doing all the work. We will show you that pan before the door covers it, because it is the only opportunity anyone will have to see it.
Our general advice is to keep original interior pairs and restore them, and to specify exterior pairs on hardware rather than on appearance. The glass in a french door is very rarely the reason it fails. The lock, the astragal and the threshold are, and all three are cheaper to get right at the beginning than to chase afterwards.
Our licensed and insured team brings the right materials and equipment to every job — glass-only reglazing inside a retained sash and frame, a Climate Zone 5A fenestration U-factor of 0.30, area-weighted averaging across a whole-house fenestration order, interior storm panels fitted over original single-pane sash, windowsill dust clearance at 250 micrograms per square foot, window well dust loading at 400 micrograms per square foot — and backs the work with a written workmanship warranty. We serve Manchester and nearby communities including Goffstown, Bedford, Hooksett, Merrimack.

Materials, equipment and how we do french doors
The difference between french doors that lasts and french doors that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with glass-only reglazing inside a retained sash and frame, a Climate Zone 5A fenestration U-factor of 0.30, area-weighted averaging across a whole-house fenestration order, interior storm panels fitted over original single-pane sash, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Manchester job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in the New Hampshire Merrimack Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Manchester Chooses Manchester Window Replacement
- ✓Every old opening gets two prices, a glass-only figure and a full replacement figure, because the federal rule treats those as different jobs and so should your quote.
- ✓We test components with a recognized kit before assuming a containment scope, since a clean result removes the requirement entirely and that saving belongs to you rather than to us.
- ✓We tell you that New Hampshire licenses nobody for this trade, then point you at the one certification that is genuinely required here and is publicly searchable by firm name.
- ✓Vertical containment on tight city lots is quoted as its own line, so you can see why an identical window costs less on an acre in Litchfield than it does off Elm Street.
