Specifications for Window Restoration Services

Every window restoration project is different, with its own specific needs and requirements, but in general, we tend to classify window restoration projects in one of the two following categories. It is common for projects to have elements of both types:

Mechanical Restoration -- to restore sound, stable windows to full operational condition:

  1. Remove window stops and window sash.
  2. Prepare all operational surfaces, removing paint build up.
  3. Replace sash cords with solid bronze sash chain (unless otherwise specified).
  4. Lightly sand the sides of the vertical sash rails and inside of the jambs. Apply a wood sealer to these surfaces.
  5. Install a weather stripping system suited to the particular window.
  6. Fabricate and install new mahogany parting beads.
  7. Install sash in a lubricated track.
  8. Install new or restored hardware, as necessary.
  9. Touch up paint, as necessary.

Shop Restoration - to restore damaged, deteriorated or unstable windows to like new and fully operational condition:

  1. Remove window sash for restoration in our shop. Stamp each window clearly to ensure replacement in correct opening.
  2. Remove all hardware. Restore or replace hardware as necessary.
  3. Remove interior stops for restoration or for exact reproduction, as necessary.
  4. Remove all paint in our "steam stripper", an apparatus which removes paint without harmful chemicals and without damaging the wood surface. Steam stripping allows removal of original glass with very little glass breakage. Original glass will be salvaged for reinstallation.
  5. Repair structural defects and surface damage to the wood using Advanced Repair 2 part epoxies.
  6. Stabilize window joints with new hardwood dowels, set in place with epoxy. Replace sections or elements of the sash, as needed. We can use select, salvaged first grown pine or similar for replacement stock.
  7. Sand all surfaces to a uniform finish and wipe down with mineral spirits.
  8. Prime all glass bedding surfaces in our dust free paint room. Oil based primer is recommended.
  9. Replace all glass using original glass or replacements. Matching replacement glass can be obtained for all eras, from seventeenth century through the 1900's. New curved glass for almost any radius is available. (Conversion of your windows to modern insulated glass may be an option for your windows. We can even possible to furnish hand blown insulated glass! Installation may require some permanent alterations to your historic millwork.)
  10. Set glass in silicone for added stability. Secure with glazing points and fix with oil based glazing compound. Allow glazing compound to dry, usually 7-14 days.
  11. Apply primer to all surfaces, allow to dry. Apply finish latex paint to all surfaces, two coats recommended. We can alter paint system specification to suit client's needs.
  12. Clean all glass!
  13. Reinstall hardware, interior stops and sash per Mechanical Restoration, above.

Jobsite Protocol -- housekeeping, security, weatherproofing.

Many of the above specified repairs will be done in your home. We promise to always remember that our jobsite is your home and that we are your guests. This means that we will use extreme care when organizing our work area, minimizing disruption to your schedule and use of the space. In all cases, we use blankets, dropcloths, Hepa vacuums and ongoing meticulous housekeeping to maintain cleanliness throughout the job.

Many of the above specified repairs require removal of the window sash to our fully equipped, 5,000 square foot shop. We will install secure, weatherproof, custom fitted temporary window closures over the window opening for the duration. If necessary, these covers can be specially equipped to admit light or air.

Complete Turnkey Window Solutions -- we can be fully accountable to you for the complete job.

In the performance of any of the above repairs, it may frequently become necessary to address additional repairs incidental to the completion to the work, such as restoration or replacement of damaged exterior sills, trim repairs, painting or masonry repairs. We can address all such repairs, either with our own forces or with long time associate tradespeople.

If necessary, we can we can also furnish hardware and weatherproofing upgrades to your windows. We maintain our own window restoration supply warehouse and showroom and can direct source a complete range of glazing, hardware, weatherproofing and storm windows. We can replace any era hardware or window glass with matching replacements.

Energy Efficiency and Sound Abatement -- to modern standards.

Your restored, original wood window can be as weatherproof, soundproof and energy efficient as any modern replacement window. There is no one answer for the weatherproofing and soundproofing of historic windows, but since we offer a full range of weatherstripping and storm window manufacturers, we can fit the solution to your needs and to the design of your particular window.

We also offer insulated glass conversions for window sash whose profiles will support it. They offer soundproofing advantages in the summer months as they are meant to be used without benefit of storm windows.

Window Replacement -- replacing the replacements.

Replacing the replacements is something we are often called upon to do. A conventional, modern "replacement window" is a temporary solution that must be replaced every 15 to 20 years as the sealed glass units fog up or the mechanisms fail. We can help you to opt out of this cycle by refitting the opening to accept quality custom window sash. We can furnish an exact match for any existing wooden sash or design. All reproduction work is done in the most durable wood species available today.
