Manchester Window Replacement provides professional casement & awning windows in Manchester, NH for residential and commercial properties across the New Hampshire Merrimack Valley. Casements seal better than anything else we install, and on Manchester's older housing they are usually the wrong thing to add. That sentence is the whole of this page, and the reason is that a casement almost never fits the opening you already have.
The sealing argument is genuine. A casement pulls its sash against a compression gasket the way a refrigerator door does, so it does not rely on the sliding contact that makes a double-hung leak as it ages. Air leakage measured at 75 pascals on a decent casement is a fraction of what a comparable slider or hung unit records.
The problem is what installing one costs on a house built for something else. Converting a tall double-hung opening to a casement means altering the opening, and altering a painted opening in a pre-1978 building is demolition of painted surface, which the federal rule expressly puts outside its minor-work definition regardless of area. You are buying a better seal and a full containment scope at the same time.
So the honest recommendation is that casements belong where they already are, and in new openings on additions where no painted historic material is involved. If your house has casements, we will fit excellent ones. If it does not, we will usually tell you to buy a well-made double-hung and spend the difference on the perimeter seal. The perimeter seal is where most of the real air leakage on an old window lives.
Awnings are the more useful of the pair here. Because the sash is hinged along its head, an awning sheds rain while standing open, and in a climate that delivers much of its precipitation sideways that means leaving one cracked through a spring storm. Over a kitchen sink, in a bathroom, or high in a stairwell they solve a real problem.
Hardware is where the money should go on either type. Operator gearboxes and multipoint keepers do the work, and a cheap operator on an otherwise good window will be the thing that fails while everything else is still fine. We name the operator and the keeper count in the scope so you can compare it against another bid.
Screens sit on the inside of a casement, which catches people out. If you are used to a double-hung, expect the screen to be part of your interior view rather than hidden behind the sash. It is a small thing and it is the single most common surprise after installation, so we would rather mention it before you order.
Where we will happily argue for a casement conversion is a modern rear addition, a sunroom, or a garden-facing wall built after 1978 where there is no lead question at all. The rules that make this a bad idea on the front of an 1890s two-family simply do not apply back there, and the performance case takes over.
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 casement & awning windows
The difference between casement & awning windows that lasts and casement & awning windows 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.
