Damage to the window sill is one of the most common problems that arise during the operation of windows. The main reasons for the appearance of defects are usually associated with careless handling, failure to follow the rules of care and recommendations for using the window sill.

Deformations occur as a result of excessive load, exposure to high temperatures, chemical reagents, and impacts. To solve the issue of restoring the aesthetic appearance of windows, different methods are used. One of the most profitable in terms of timing and financial costs is window sill repair using special overlays.

What types of repair pads are there?

Repair linings for window sills come in different textures, colors, and sizes. The main material is PVC. The standard length of restoration panels is up to 3 meters, depth - up to 1.5 m. During the repair work, the linings are simply cut to match the parameters of the window sill. The color range includes white, black, woodgrain, light gray and other shades.

Surface design is optional. The overlay for a window sill made of artificial stone, concrete, wood, plastic can be matte or glossy. If necessary, custom production in any design and size is possible. To complete the decorative design, additional elements are used - colored or white end caps.

Installation of repair pads

The main advantage of restoration panels is ease of installation. The process is not complicated, does not take much time and does not involve a large amount of work. The best option is to contact specialists who will carry out restoration work in the shortest possible time, carefully and efficiently.

If you have the necessary tools and experience, you can perform the repair yourself. Installation of repair pads is carried out using mounting adhesive. The joints are filled with silicone. To cut the panel to fit the size and shape of the window sill, you need a jigsaw or a fine-toothed saw.

Main stages of work:

  1. Preparing the window sill - the surface must be smooth, dry, clean, and free of grease;
  2. Cutting PVC panels - the size is adjusted according to the parameters of the window recess, taking into account all the shaped fragments;
  3. Applying glue - uniform distribution of the adhesive layer over the entire surface;
  4. Installation of the overlay - for a strong fixation, the panel is pressed tightly over the entire surface, a “weight” is installed in the corners and problem areas until the glue dries completely;
  5. Installation of plugs - remove the edges of the protective film and install end and side plugs;
  6. Processing of joints - the joints of PVC panels with the window frame and slopes are filled with silicone;
  7. Preparation for use - after complete drying, the protective film from the lining is completely removed.

Installing a window sill trim in an hour with your own hands

Materials and tools. Window sill trim, end caps, assembly glue or liquid nails, degreaser (solvent), sanitary silicone, fine-tooth hand saw, ruler, pencil.

1. We buy an overlay of standard length and width at the point of sale and at home; if necessary, we adjust it to the individual size of the window sill ourselves

2. Measure out the required size and mark the cutting location.

3. Place the overlay on a stable stand, for example, made from two stools, and use a fine-toothed saw to cut off the excess.

4. The side edges of the trim should be adjusted to the window opening - cut out a paper template, and then cut the trim using this pattern.

5. Apply mounting adhesive to the window sill, cleaned with a degreaser (solvent), forming straight sections along the edges and a wide zigzag in the middle.

6. Install the trim on the window sill, and then lightly press it all.

7. After placing the trim on the window sill, press it along its entire length, and then place a load on it, for example, stacks of books. It is important that the load on the side edges is quite strong.

8. After 15-20 minutes, remove the weight from the window sill and the transparent protective film from the surface of the lining.

9. Carefully fill the gap between the cover and the wall with silicone from the cartridge. Smooth the freshly applied seam with a finger moistened with water.

10. Select ready-made plugs to match the color of the overlays. We measure, cut them with a saw and glue them to the side edge of the window sill trim.

11. We also fill the gap between the side edges and the wall with silicone, and carefully smooth the seam.

Universal end caps are also used, suitable for any window sill size, which further simplifies its restoration.

Note that modern production of such linings appeared on the Russian market in the Moscow region not so long ago. But, unfortunately, this product remained unclaimed in the Russian window market. If someone is looking for a business idea to expand their entrepreneurial activities, then this niche is free.

Pros and cons of repairing a window sill using a trim

Complete replacement of a window sill is a labor-intensive and expensive process. Repair pads provide significant savings, both in terms of time and costs. In this case, the interior decoration of the room is not affected during the installation work. There is no need to re-glue the wallpaper, as is often required after installing new window structures, in the case of overlays.

The operational properties of PVC linings are also an advantage.
The surface is resistant to sunlight, moisture, and temperature changes. The only negative is that it is not always possible to use panels for repairs. If the window sill is completely broken - cracked in half - then it is advisable to replace it with a new one. In general, repair linings are the best option when you need to update your interior and hide any surface defects. This is a convenient and inexpensive solution for restoring the aesthetics of the window sill and the appearance of windows in general.
