Wood Window Repair

Despite being crafted at their best quality, wooden windows will inevitably encounter issues in the long run. However, there are some methods in fixing them.

To start, window repairs are classified into two principal categories, namely, window frame and sash fixing and window glass repairing or replacing. But at this point, the main focus is on solving window frame and sash problems.

The window sash belongs to the window portion that keeps the glass in place. It may either be fixed or operable, although problems may ensue on both forms. Operable windows, on the other hand, endure more problems due to their mechanisms. Even though this type may remain durable for years, time has its way of making things unruly.

Compared to metal windows that have lesser issues brought about by the weather, wood windows deteriorate upon damp exposure and crack upon sun exposure. Aside from that, wood is prone for termite infestation.

Double-hung windows, wherein the bottom section can be raised and the top section can be lowered, are most commonly damaged if they are made of wood. Opening them becomes hopeless once they are affected. But this window type can be preserved by repainting its wooden frames for 3 to 5 years, depending upon the dominant weather, and by caulking the edges and filling the cracks yearly.

In the case of vinyl and aluminum windows, basic maintenance is needed to keep them functional. Scrubbing them with a natural bristle brush and detergent solution is enough. For anodized aluminum frames, fine steel wool can be used for polishing, and paste wax can be used to coat them after.

Rotten Woodwork Repair

When the weather heavily injures a wood sill or sash leading to rot, epoxy wood fillers, bought in home centers, can be used for repair. But if majority of the wood is affected, consider section or entire sash replacement by contacting window replacement companies such as the Glass Guru.

If window damage is manageable, a chisel can be used to remove the rotten parts. Next, few ¼-inch holes can be drilled to the damaged part. The said part is then entirely soaked with liquid epoxy “consolidant” for it to become sturdy while allowing the liquid to be absorbed for about 5 minutes. The consolidant can be reapplied repeatedly until the wood stops accepting it. After which, epoxy fillers are mixed, while following label instructions, so as to begin the molding process. Then, an old putty knife or a flat paint stirring stick is dipped on the solvent before packing and shaping the repair as the material dries. Once done, the repaired area is filed to smoothen and flatten it. Since the filler is less pliable, irregularities on the surface area may occur despite filing. An exterior-grade vinyl compound can be applied to fill the holes and voids present. At this point, the material can be dried and filed repeatedly to smoothen it. Lastly, within 3 days, the material can be primed and painted.

A Stuck Double-Hung Window

Double-hung windows might get stuck in their tracks oftentimes due to accumulated grime, high humidity that causes wood swelling, or frequent repainting that seals the surfaces together.

Temporarily Stuck Double-Hung Window

High humidity can stuck the window sash temporarily and solving this involves simply waiting for a change in weather. If sash movement is reluctant, clean its channels, and if the channel presses against the window, insert a wood block and strike it using a hammer.

Remove channel blockage caused by grime by using a sharp wood chisel. Next, sand the channel using medium sandpaper that is wrapped around a wood block. Lastly, coat the channel with wax for lubrication.

If budging the window is difficult, cut the sash’s painted edges using a utility knife. Afterwards, tap a 3-inch-wide putty knife between the frame and sash using a mallet. Then, wedge the said knife between the sill and sash, alternately working on both corners to evenly move the sash upward. Use a wood block for sill protection.

A Painted Shut Double-Hung Window

For this scenario, cut through the paint that seals the sash around to ensure window functionality.

In detail, slice through the paint surrounding the movable sash using a utility knife, not leaving behind any uncut areas both inside and out. Painted surfaces must not be damaged.

Using the heels of the hands, abruptly open the window, making sure that the window is unlocked and no nails or screws secured the sash to the jamb. Remove if found any.

If failure persists, free the window carefully using a mallet or hammer on a wood block. Ensure not to break the glass in doing this technique. Remove the loose paint away once the window is opened.

Loose Window Sash

Though occurring occasionally, this scenario is the complete opposite of stuck windows. It happens primarily because wood shrinks to a certain point and continues to wear upon usage. As a result, the window rattles in its tracks. However, too much loosening of a sash can be tightened by slightly adjusting the stop without removing it if the stop is nailed instead of screwed and if the gap is not wide enough.

Paint can be scored between the jamb and the stop, and a cardboard shim can be inserted midway of the sash and the stop. For stop protection, a wood block can be held against it while hammering is done towards the sash, following the stop’s length, until the paint film tears and the stop rests against the shim.

Adding an insulation strip to the old parting strip’s face is another easy method because it may receive enough window slack while protection against the elements is added.

Window Falls Shut

A broken sash cord is the main reason why double-hung windows keep on falling upon opening. To solve this, take away the interior stops first. This is done by slicing the paint seal using a utility knife and by prying off the moldings with the help of an old chisel. Remove any weather stripping if present. Second, set the sash cords aside and tilt the bottom sash out. Carefully lower the weights if both sash cords are intact. Upper sash cord replacement can be done by prying out at least one of the parting strips to remove it. Prying out parting strips results to their damage, but new ones can be purchased at a lumberyard. Third, covers of the access panel, found at the window frame’s inner face, must be removed. Fourth, place a new #7 cord above every top pulley and feed it down until the access reached. Utilize a bent coat hanger in pulling through the access hole as needed. Fifth, tie the cord’s end on both sides onto the sash weight. Then, pull the cord taught, with its weight that sits on the bottom of its channel. From the top pulley, trim around 4 inches of it. Sixth, make a knot and push it towards the top slot at the sash’s side. With a brad, tack the knot, and inspect the window’s up and down action. Finally, perform window reassembly following the reverse order of disassembly, making sure the stops are not tight enough to prevent the window from binding.

Window Sill Protection

Because the sill extends out from the window, it is the most damage-prone part of the frame. To ensure an easy and excellent protection, cover the sill with aluminum sheet and paint it for aesthetic purposes.

Create a paper template to fit in the sill. Lay the template on the aluminum sheet and trace its pattern on the sheet. Cut the traced pattern afterwards. Do caulking on the sill edges, and wedge the aluminum’s one side to the sill’s stool and securely nail it using 1-inch roofing nails. Secure a wood block over the aluminum’s surface, and strike a hammer over it for the aluminum to follow the sill’s shape. Underneath the seal, nail it, and along the caulking compound, seal it along the edges. Lastly, using a metal primer, do priming and paint it to achieve trim matching.
