Expert fitters can encourage on acoustic glass or different thicknesses of panes to minimize street noise-- a typical requirement for city-dwellers in period homes.

Indications You Need a Professional Fitter vs. Basic Repair
| Symptom | Potential Cause | Expert Requirement |
|---|---|---|
| Rattling in the wind | Used staff beads or absence of seals | Fitting of draught-proofing system |
| Sash won't stay up | Damaged cord or inaccurate weights | Replacement of cables and re-balancing |
| Visible rot in the sill | Water ingress | Partial or complete frame replacement |
| Condensed glass | Blown seal in double glazing | Replacement of glazing unit |
