PVC Window Service & Repair

Window drafts, condensation, or broken hardware? We fix it.

Ecoventi specialises in PVC window servicing – seal and glass replacement, hardware adjustment, draught and condensation removal. We work with Inoutic/Deceuninck Eforte, Prestige and Arcade systems.

What we solve

Most window problems do not require full replacement

Draughts, condensation between panes, stiff hardware – these are common faults we fix on-site. Full window replacement is unnecessary and more expensive than servicing in most cases.

We work with Eforte, Prestige and Arcade systems, so we know their construction, seals and hardware in detail. We arrange a service visit quickly, without long waits.

What We Actually Do

Three types of intervention. Most issues are solved without replacing the window.

Drafts and cold frames

Gasket Replacement

The gasket is usually the first part to wear out. Replacing it is the most cost-effective fix for standard PVC windows, regardless of brand or profile.

  • suitable for common PVC profiles
  • roughly one hour per window
  • restores the original sealing performance
  • no frame or trim replacement required
Condensation between panes

Insulated Glass Replacement

When the spacer fails, condensation between the panes cannot be cleaned away. We replace the insulated glazing to the exact size of your window without removing the frame.

  • measured on site and made to size
  • standard and non-standard dimensions
  • no frame or trim replacement required
  • restores thermal performance
Stiff hardware and poor closing

Hardware Service

Most hardware problems do not require full replacement, only proper adjustment. Correctly calibrated hardware helps the window close tightly and operate smoothly.

  • suitable for common hardware systems
  • adjustment without replacing parts in many cases
  • worn components replaced when necessary
  • often completed in a single visit
How We Work

Window service without guesswork or unnecessary replacement

We first identify the real issue, then recommend the most sensible intervention. In most cases that means service, not full replacement.

Step 01

You contact us

Describe the issue and, if possible, include a photo. The first symptoms are often enough for us to estimate whether the issue is related to gaskets, glazing, or hardware.

Step 02

We inspect the window on site

During the visit, we assess the technical condition, test functionality, and tell you whether a service intervention is enough or whether a part needs to be ordered precisely.

Step 03

We recommend the right fix

If adjustment or gasket replacement is enough, we handle it as a service job. If new insulated glazing is needed, we measure it precisely and explain the next step clearly.

Step 04

We repair and calibrate

The goal is simple: the window should seal properly again, close correctly, and work without drafts, condensation, or unnecessary effort.

Smart Decision

Not every damaged window needs to be replaced

When repair is usually enough

  • the window is drafty but the frame is still sound
  • moisture forms between the panes
  • the handle feels stiff or the sash closes poorly
  • the hardware needs adjustment or a worn part replaced
  • the gasket is hard, cracked, or no longer seals correctly

When replacement starts to make sense

  • the frame is significantly damaged or deformed
  • the window has repeated serious failures in several parts
  • the technical condition is beyond economical repair
  • it is an outdated system with no meaningful service path

If a window can be repaired reliably and sensibly, we recommend service. We only suggest full replacement when it is genuinely justified.
