Window Restoration Services

Historic Window Schematic Drawing Click to Blow Up.

Every window restoration project is different, with its own specific needs and requirements, but in general, here is an overview of what might be improved when we tune up a wood double hung or steel casement window:

Double Hung Windows May Require:

1. Complete sash removal.
2. Release of tightness caused by excess paint and misalignment.
3. Installation of new rope, chain, or balancer.
4. Reinforcement of all loose joints in the sashes. Caulking is needed to keep the joints form deteriorating any further. Epoxy restoration may be needed for badly rotted joints.
5. Replacement of parting beads that may be cracked, rotten, or warped.
6. Re-weighing the sash to make sure the counterbalance weight is correct.  There has to be no dropping down or floating up in a sash.  It should be suspended in space.
7. Lubrication of channels and pulleys which should solve squeaking and sticking.
8. Realignment of locks and stops.  Stops are vertical strips of wood which control the bottom sash.  They should be lined up to allow the sash to have just enough clearance for free movement, but not too much.  When they are totally closed, they should touch the top rail of the bottom sash to keep the assemebly still. This will prevent rattling when the window blows.
9. Installation of weather-stripping if required or requested.  This will also increase energy efficiency and make the window seem smooth.
10. If the sashes are irreparable because of dry rot or termite damage, replication and installation of new sashes which will identically match the old sashes and keep the look of the house consistent.

WOOD CASEMENT WINDOWS: Removal of window sashes

1. Re-fitting of  window sashes to window frames allowing room for painting.
2. Re-installment or tightening of parliament hinges or door hinges. Lubrication of hinges for smooth operation.
3. Reinforcement of all loose joints in the sashes. Caulking is needed to keep the joints from deteriorating any further. Epoxy restoration may be needed for badly rotted joints.
4. If the sashes are irreparable because of dry rot or termite damage, replication and installation of new sashes which will identically match the old sashes and keep the look of the house consistent.
5. Installation of external copper material (both vertical and horizontal if necessary) to help divert water from entering the house.
6. Opening of weep holes to allow water to properly drain from window frames and sills.
7. Installation of hardware to better secure the windows as well as make the windows more airtight. (upon request).
8. Cutting of a small slot in the jamb to allow for inconspicuous removable silicone weather-strip.

STEEL CASEMENT WINDOWS:

1. Refitting and adjustment of sash for easy one-hand operation.
2. Weather-strip of window if needed.
3. Lubrication and adjustment of original hardware.
4. Installation of new hardware if necessary.

Function, Quality and Longevity of Old Windows versus New

Before

After

Your wood windows are an original and irreplaceable part of maintaining the historic integrity of the building.

Hang on to those old windows!

Function

Many people assume that the only way to get their old windows to function and perform like new windows is to replace them. This is simply not the case. We can make your existing windows work like new at less cost, and weatherize them with modern insulating material to make them perform like new windows.

Quality

Your original wood windows were hand built by skilled craftsman. Special care was taken to match window trim and sash profiles to other architectural features of your building. Their proportions were specifically designed to be appealing to the eye and to be integrated into the general appearance of the building.

Longevity

Your windows were made of old growth lumber from virgin forests. Old growth lumber is more dense and enduring and has a natural resistance to decay. There are many reasons why your windows have lasted a hundred years or more. You can expect a hundred more years with proper restoration or repair.

Did you know that old windows are just as energy efficient as new windows? They are also a better investment. Even though they may require some maintenance, they will never require complete replacement as all replacement windows will. Replacement windows are not an investment that will last a lifetime (the way the old windows already did), because they are made of plastic. Replacement windows have


• Springs that will lose their spring

• Strings that will break

• Plastic parts that will fatigue and crack

• Double paned glass that will fail and cloud
