Planning a window replacement or repair in Perth? Window Specialists can fit new units, replace glass and adjust or repair frames. Share the number of windows, sizes and whether any are at height. This helps a window-specialist plan access and give an accurate quote.
Tell window-specialists about your window issue and request quotes. Include the number of windows, timing and any access challenges or restrictions. Describe the job and get quotes to check availability.

WINDOW POINTERS
Worth knowing before you plan the work, set a budget and hire a Window Specialist.
WORTH KNOWING
New-build glazing has to meet Part L from the outset, same as replacement windows, and is usually specified alongside the wider build rather than as an afterthought — window position and size affects room lighting and ventilation calculations the rest of the design depends on.
SAFETY & COMPLIANCE
Do I need a certificate for a single window replacement? Yes, the same Part L rules apply whether it's one window or the whole house. Can I fit my own windows? Technically yes, but you'd then need a separate council building control inspection, which most installers' FENSA/CERTASS registration avoids automatically.
COST & QUOTES
An initial quote is usually based on rough measurements and photos; a firm price follows an in-person survey, since window openings in older properties are rarely perfectly square or a standard size. Made-to-measure lead times are typically 2-6 weeks after survey, before installation is booked in.
RULES & STANDARDS
A proper quote should state frame material and colour, glazing spec, whether old windows/frames are removed and disposed of, the FENSA/CERTASS certificate, and the guarantee length on both frames and glazing units, which can differ.
WORTH KNOWING
If the frame and seals are otherwise sound, draught-proofing strips and secondary glazing can meaningfully cut draughts without full replacement — worth considering before committing to new windows, particularly on a period property where replacement is restricted anyway.
USEFUL TO KNOW
French doors suit a more traditional look and a narrower opening than bifold or sliding doors, but both leaves typically need to open for full access, unlike sliding or bifold options. The right choice often comes down to the room layout and how the space is actually used day to day.
USEFUL TO KNOW
Toughened (safety) glass is required by Building Regulations in doors and low-level windows. Laminated glass adds security and noise reduction. Obscure (patterned) glass is used where privacy matters, like bathroom windows, without losing light — worth specifying which you need per opening rather than assuming standard clear glass throughout.
RULES & STANDARDS
A quote well below others is worth questioning — check it specifies the same glazing spec (U-value), includes the FENSA/CERTASS certificate, and covers disposal of old windows. High-pressure doorstep sales tactics and "today only" pricing are worth treating with real caution in this trade specifically.
LOCAL AREA
Perth was seriously considered as a capital for an independent Scotland at points in its history, and its position on the Tay gave it the trading importance to back that up. The historic centre around the river holds Georgian and Victorian building stock, while the suburbs spreading out from it are considerably more standardised twentieth-century construction. As with several riverside towns, low-lying ground near the Tay is worth a flood-risk check before any groundworks, a step that doesn't apply further from the water. Perth's role as a market town for the surrounding area has also kept newer housing coming on its outskirts.
Perth’s Georgian and Victorian riverside buildings and more standard suburban stock demand different window solutions: the historic centre often requires timber sash repairs or bespoke timber replacements to preserve period character, while suburbs typically accept modern uPVC or aluminium units to improve thermal performance. Installers registered with FENSA or CERTASS can self-certify Building Regulations compliance for glazing and ventilation requirements, which simplifies paperwork for replacement windows. In conservation areas near the Tay, there may be tighter controls on frame materials and appearance, so choose specialists experienced with like-for-like conservation installs and sympathetic detailing.
Secondary glazing is a common solution in listed or historic properties where full replacement is not permitted, offering improved thermal and acoustic performance without altering external appearance. For modern homes, double- or triple-glazed units can be specified to meet energy-efficiency goals and acoustic needs from riverside exposure. When hiring a window specialist in Perth, request FENSA/CERTASS registration, examples of timber work in Georgian or Victorian buildings, and proposals that respect any conservation constraints. Expect a measured survey that covers sightlines, historic profiles and ventilation requirements.
