Plastic window adjustment
Ivan master po remontu okon Tbilisi
Plastic windows lose their airtightness over time: drafts appear, sashes stick or close improperly. In Tbilisi, where temperature fluctuations and humidity are higher than in temperate zones, these problems occur more frequently. Window adjustment is a set of precise hardware and sash geometry settings that restore the product to factory parameters. During the work, the master checks the sash compression, hinge position, and gaps around the perimeter. Components such as eccentric cams (pins), strike plates, scissors, and adjustment screws are used. In Tbilisi, adjustment against seasonal deformation is especially relevant — in summer windows should close tightly against dust, in winter they should retain heat. You should contact a specialist at the first signs: difficult opening, sash sagging, handle sticking, or whistling from the seal. Self-adjustment without experience often leads to damage to expensive hardware (Roto, Siegenia, Maco). Master Ivan with 8 years of experience performs adjustment quickly, with a work guarantee. Geo-targeting to Tbilisi: I service the districts of Vake, Saburtalo, Didube, Chugureti, as well as surrounding areas (Mtskheta, Gardabani). I work with both apartments in new buildings and old houses where plastic windows are installed in wooden openings.
How the work is done
Inspection of the window structure: checking all sashes, hinges, seals and hardware. Identifying the causes of malfunction: wear, dust accumulation, misalignment of the window opening.
Removal of dirt and old lubricant from guides, hinges and mechanisms. Application of fresh silicone lubricant — this reduces friction and prevents corrosion.
Using the adjustment screw in the lower hinge, the sash is raised or lowered so it becomes parallel to the frame.
Using the screw in the upper and lower hinges, we shift the sash left/right, eliminating diagonal misalignment.
Rotating the eccentric cams (pins) on the sash edge. The necessary compression is set depending on the season.
Adjusting the position of the strike plates on the frame for precise engagement with the eccentric cams. Ensures airtight closure without gaps.
Adjusting the fastening of the upper and lower hinge, as well as the scissors (tilt system). Eliminates sagging and wobbling.
The handle should not stick when turning. If there's play — tighten the screws or replace the handle.
Opening and closing the sash in different modes, checking fit with a sheet of paper. Ensuring there are no drafts.

Tips from the pro
- Adjust compression twice a year: increase in winter, decrease in summer — this extends the seal's life.
- Do not allow dirt to accumulate in the guides — regularly clean windows without using abrasives.
- If the handle turns stiffly — do not apply force, this is a sign of wear. Call a master for lubrication and adjustment.
- After adjustment, check airtightness with a sheet of paper: pinch the sheet with the sash, if it pulls out easily — compression is weak.
- When replacing a glass unit, always call a master for adjustment — a new unit may change the sash geometry.
- If your window faces a noisy street, use reinforced compression mode — this will reduce noise by 2-3 dB.
