Replacement of hardware with tilt-turn function (winter-summer)
Ivan master po remontu okon Tbilisi
Window hardware wears out over time, loses its seal, and stops performing its functions. This is especially noticeable when the sash no longer presses tightly against the frame, drafts appear, condensation forms on the glass, and ventilation is only possible by fully opening the window. The solution is to replace standard pivot hardware with tilt-turn hardware featuring a "winter-summer" function. This modernization transforms an ordinary fixed or pivot window into a multifunctional structure: the sash can tilt for micro-ventilation from above, and the pressure mode allows you to adjust the force of the sash clamp depending on the season. In Tbilisi, where the climate features mild winters and hot summers, such a mechanism is particularly relevant: in winter you prevent heat loss, in summer you ensure comfortable air intake. Humidity in the city near the Mtkvari River is often high, and improper hardware adjustment can lead to mold appearing on the slopes. Professional installation of a set of components — rods, scissors, main lock, response plates, and cams — makes it possible to fine-tune the sash pressure around the perimeter. Only certified systems from German or Turkish brands are used (Roto, Winkhaus, Maco, Kale), compatible with your window profile. I perform work with on-site visits throughout Tbilisi — from the Vake and Saburtalo districts to Avlabari and the Old City. On-site visit and diagnosis are free. Warranty on work is 1 year. Savings on heating and a comfortable microclimate in your apartment or office — that's what you get.
How the work is done
I arrive at a convenient time in any district of Tbilisi, inspect the window, check the condition of the profile, seal, and hinges. I determine the type and size of the hardware and select a compatible set.
I carefully remove the sash from the hinges and unscrew the old latch plates, scissors, and locks. I check the condition of the grooves — if necessary, I clean them of dust and plastic residue.
I attach the main plate with cams to the sash, align it by factory marks. I install an incorrect action blocker to prevent handle breakage.
I hang the upper scissors on the sash and frame, adjust the tilt angle. I check that the sash opens without effort and locks in the tilted position.
I attach response plates to the frame opposite the cams. I position them taking into account the pressure: for "winter" and "summer" modes, the plates may have depth adjustment.
I put the sash on the lower hinge and snap the upper hinge (if present). I adjust the hinges vertically and horizontally so the sash stands level, without skewing.
I turn the cams to the desired position: eccentric marking toward the seal — winter (reinforced pressure), away from the seal — summer (weak). I check the tightness with a piece of paper.
I test all functions: opening, tilting, locking, handle in 3 positions. I explain to the client how to switch modes and provide care recommendations.

Tips from the pro
- Check the condition of the seal before replacing hardware: if it has hardened or cracked, order a replacement at the same time — otherwise the pressure won't be airtight.
- Adjust the cam pressure twice a year — in spring and fall. It takes a minute (4 mm hex wrench), but extends the life of the seal and reduces heat loss.
- After installing new hardware, don't lubricate mechanisms with thick oils — they clog the grooves. Use silicone lubricant or WD-40.
- Don't apply excessive force when turning the handle: if it sticks, the blocker hasn't disengaged or the sash is skewed. Call a specialist — a broken handle may require replacing the entire lock.
- If your area (for example, Didube) often experiences power outages and humidity fluctuations, I recommend installing an additional protective plate against sash sagging.
- When modernizing several windows, do them sequentially — this way the specialist can set a uniform pressure level and synchronize the mechanisms.
