Built for Comfort, Finished for Your Home

Types of Double Glazing for Different Windows We Handle

Casement Windows: Casement windows are side- or top-hinged and open outward. They press tightly against the frame when closed, creating an exceptional airtight seal that maximises the thermal performance of double glazing.
Tilt and Turn Windows: Feature a dual-hinge mechanism that tilts inward for secure ventilation or swings fully inward. They work exceptionally well with double glazing on upper floors because you can clean the outside glass safely from indoors.
Vertical Sliding (Sash) Windows: Traditional sliding Sash windows use modern spring balances and slim double-glazed units. They maintain the historic character of period properties without sacrificing energy efficiency.
Flush Casement Windows: These windows sit level within the frame for a clean, minimalist look, ideal for both contemporary and traditional properties when paired with modern double-glazed panes.
Bay and Bow Windows: Projected outward from the building, combining multiple double-glazed panels to increase natural light and interior space.

 Trustindex verifies that the original source of the review is Google. Outstanding Service from RR Double Glazing Ltd!

I recently used RR Double Glazing Ltd to repair some faulty double glazed windows in my home, and I couldn't be happier with the results. From start to finish, the service was professional, efficient, and hassle-free.

The team at RR Double Glazing quickly diagnosed the issue—misty panes and worn-out seals—and offered a clear, affordable solution. They arrived promptly, were courteous and tidy throughout the job, and completed the work to a very high standard. My windows now look as good as new, with no more condensation or drafts.

What impressed me most was their honesty and attention to detail. They didn't try to upsell anything unnecessary and made sure I was 100% satisfied before leaving. It’s clear they take real pride in their work.

I would highly recommend RR Double Glazing Ltd to anyone needing window repairs. Reliable, skilled, and friendly—exactly what you want from a local company!

Give Old Windows a Clearer Future

Our Core Installation Process for Double Glazing

Survey and Measurement: Our experienced technicians accurately measure the window opening to manufacture a custom double-glazed unit (DGU).
Removal of Old Windows: Our licenced and fully qualified installers carefully take out the existing sashes and old frames without damaging the surrounding brickwork or interior plaster.
Preparing the Opening: We thoroughly clean the reveal, clear out all the old debris, and check and fit damp-proof membranes or sill boards.
Securing the New Frame: Our certified experts precisely level, plumb, and anchor the new uPVC, aluminium, or timber frame into the wall firmly using heavy-duty fixings.
Fitting the Sealed Units: We professionally and carefully insert the double-glazed glass panes into the frame and lock them securely in place with internal glazing beads.
Sealing and Finishing: We apply weatherproof silicone sealant and expanding foam around the exterior and interior gaps to block drafts and water, followed by tidy trim work and compliance certification.

FAQ's

Frequently Asked Questions

Why has my double-glazed window become cloudy?

Cloudiness or misting between the panes usually indicates that the sealed unit has lost its integrity and moisture has entered the gap. In many cases, the sealed glass unit can be replaced without removing the entire window frame.

Can you replace a failed glass unit without replacing the window frame?

Yes, provided the existing frame remains structurally sound and is suitable for the replacement unit. RR Double Glazing supplies and fits replacement sealed glass units, making glass-only replacement a potential alternative to installing a completely new window.

What is the advantage of replacing only the glazing?

Keeping a usable frame can reduce unnecessary disruption and avoid the cost of replacing components that are still in good condition. A new sealed unit can restore clarity and improve the window’s insulation without requiring a complete frame replacement.

How can I tell whether my window needs repair or complete replacement?

The condition of the frame, hinges, locks, handles, seals, and glazing all need to be considered. A damaged sealed unit may only require glass replacement, whereas extensive frame deterioration or multiple component failures could make replacement more appropriate.

Are uPVC windows suitable for upgrading to modern double glazing?

Yes. Existing uPVC windows can sometimes accommodate replacement sealed units, depending on the frame design and dimensions. RR Double Glazing works with uPVC windows and provides double-glazed glass replacement and related repair services.

What should I do if my double-glazed window is letting in a draught?

The source should be identified before replacing the whole window. Worn seals, poorly aligned opening sections, damaged hinges, or problems around the frame can all contribute to draughts. An inspection can establish whether adjustment, component repair, resealing, or glazing replacement is required.

Can faulty hinges affect the performance of a double-glazed window?

Yes. Worn or damaged hinges can prevent the sash from closing and sealing correctly, which may affect operation, security, and resistance to draughts. RR Double Glazing provides hinge replacement and repairs for relevant window systems.

Can you repair a double-glazed window that will not lock properly?

Yes. Faulty locks, handles, and locking mechanisms can be inspected and repaired or replaced where appropriate. Correct alignment of the opening section is also important because a mechanical fault is not always the only reason a window fails to lock correctly.

How are replacement double-glazed units measured?

The required unit needs to match the existing opening and glazing specification accurately. Measurements are taken before manufacture so that the replacement sealed unit can be produced to the required dimensions. RR Double Glazing also supplies made-to-measure sealed units.

What determines the cost of double glazing in East London?

The cost depends on whether you need new windows, replacement sealed units, repairs, frame work, hardware replacement, or a combination of services. The number and dimensions of windows, glazing specification, frame material, access, and installation complexity can also affect the final quote.
