Find Local SpecialistsCommon Window Problems in Marlow Properties
Older and poorly maintained windows present a range of problems that affect comfort, security and energy costs. Condensation between the panes is one of the most common issues — it indicates a failed seal in the double-glazing unit and cannot be fixed by cleaning. Draughts around the frame suggest worn or missing seals, subsidence or a poor original installation. Rotting timber frames, broken or stiff handles, failed locks and fogged glass are all signs that repair or replacement may be needed.
Window specialists in Marlow can carry out a diagnostic survey, advise whether repair is viable and provide a fixed-price quote for whichever solution is appropriate.
FENSA, CERTASS and GGF Membership Explained
FENSA (Fenestration Self-Assessment Scheme) and CERTASS are the two main competent person schemes for window and door replacement in England and Wales. Membership allows approved installers to self-certify that their work complies with Building Regulations, without the homeowner needing to apply to the local council. The Glass and Glazing Federation (GGF) is the trade association for the glazing industry, and GGF membership indicates a company that subscribes to its code of conduct.
All window specialists in our Marlow directory are checked for active registration with at least one of these bodies, so your installation will be compliant and certificated.

FENSA Registration and Compliance Costs for Windows in Marlow
When a FENSA or CERTASS registered installer replaces windows in Marlow, a registration fee is payable to the competent person scheme to cover the cost of issuing your compliance certificate. This fee is usually modest and is typically included within the installer's quote rather than charged separately — but it is worth confirming this when comparing proposals.
If a window company you are considering is not FENSA or CERTASS registered, you would need to apply to the local authority building control department yourself and pay their associated fees. This route also involves an inspection visit, adding both cost and delay to the project. Using a registered Window Specialists avoids all of this.
Frequently Asked Questions — Timescales for Window Installation in Marlow
A typical three-bedroom house with 8–12 windows can usually be completed by an experienced two-person team in one to two days. Larger properties, complex openings or additional doors will take longer. Your installer will confirm timescales during the survey.
Standard uPVC windows are typically manufactured within 2–4 weeks of order. Aluminium, timber or bespoke units may take longer — sometimes 6–8 weeks or more. Ask for a confirmed lead time in writing when you accept the quote.
Someone should be present throughout, particularly for security reasons while openings are exposed. The installation team will need access to all rooms where windows are being replaced. Most installations can be scheduled around your commitments.
An individual casement window replacement typically takes between one and three hours depending on size, access and any complications with the existing installation. Bay windows and large feature windows will take longer.
FENSA-registered installers have 30 days from completion to submit the installation to FENSA. Your certificate is then issued and posted. If you haven't received it within six to eight weeks, contact your installer or FENSA directly.
