What We Do

Pocket window installation that helps Home owners reduce disruption during glazing upgrades

Includes frame suitability survey, custom measurement, retrofit insertion, foam sealing and caulking.

  • Retrofit Insertion & Fitting

    Insert double-glazed units into existing frames with precise measurement.

  • Sealing & Infiltration Prevention

    Foam and caulk seals to reduce drafts and improve weather resistance.

Why Havering Double Glazing

Survey-led pocket installations with itemised written quotes

A poor retrofit can leave gaps, drafts and water ingress; a proper survey and sealing plan prevents those failures.

Common Challenges

  • Uncertain frame suitability for pocket inserts

    Without an on-site survey a pocket unit may not fit correctly. Misfits cause drafts, sticking sashes and extra expense for repairs.

  • Gaps, drafts and condensation from poor sealing

    Havering's high humidity and coastal salt air speed seal deterioration, which leads to condensation, rot risk and ongoing comfort issues.

  • Sizing limits compared with full-frame options

    Retrofit sizing can restrict sightlines and hardware choices on terraces and semis, so careful measurement is needed to match appearance.

How We Help

  • Typical one-day installation per opening

    Pocket installs usually finish in one day per window, reducing time on site compared with full-frame replacements.

  • Retains existing trim and interior finish

    Pocket insertion keeps original trim intact, avoiding redecorating and preserving the character of terraces, semis and flats.

  • Foam and caulk weatherproofing

    Specified foam seals and high-grade caulking restore airtightness and resist Havering's coastal salt air.

  • Itemised written quote before works

    We provide an itemised quote showing materials and labour so you can compare pocket and full-frame costs clearly.

    We inspect frame condition, measure openings and confirm retrofit viability, noting any repairs required before quoting.

  2. Itemised proposal

    We issue a written, itemised quote listing materials, labour and the recommended sealing method to meet performance needs.

Frequently Asked Questions

Questions Havering customers commonly ask about pocket installation

Practical answers on suitability, timing, compliance and risks to help you decide.

Failed seals let moisture and cold in, causing condensation, timber rot and higher heating bills. In Havering's humid, coastal climate damage accelerates, and long-term repair can require full-frame replacement rather than a simple reseal.
Delaying can allow seal and glazing problems to worsen, increasing the chance of water damage and the need for larger repairs that cost more than an early insert and reseal.
We carry out an on-site survey to check frame squareness, timber condition and reveal depth. If frames are sound we confirm retrofit fit and provide an itemised quote.
Most pocket insertions do not need planning permission, but conservation areas or listed buildings may have restrictions. We advise checking local council rules before work.
Yes. We are a FENSA approved installer and issue the relevant certificate on completion so your replacement is recorded for future compliance.
Typical pocket installs are completed in one day per opening, subject to site access and any preparatory repairs found at survey.
With accurate measurement and suitable unit selection, pocket inserts can match sightlines and hardware closely; some style or sizing limits may still apply on older terraces.
