Professional fitters can recommend on acoustic glass or various thicknesses of panes to reduce street noise-- a typical requirement for city-dwellers in duration homes.

Indications You Need a Professional Fitter vs. Basic Repair
| Sign | Potential Cause | Expert Requirement |
|---|---|---|
| Rattling in the wind | Used staff beads or lack of seals | Fitting of draught-proofing system |
| Sash won't keep up | Damaged cable or inaccurate weights | Replacement of cords and re-balancing |
| Visible rot in the sill | Water ingress | Partial or full frame replacement |
