About our glazing silicone in Beckenham
Glazing silicone is a maintenance item. Weather and movement take their toll, and once it cracks, water follows. Resealing puts that right. If you’re dealing with cracked silicone between glass panels and leaks where conservatory glass meets the frame, we can help.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
All our work comes with our one-year guarantee.

Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
If you manage several properties in or around Beckenham, several properties can be quoted together. Just tell us the addresses and what each one needs.
Why deal with it now?
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Beckenham.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

How the job changes by surface
Shower screens
Black or peeling silicone on a screen lets water out. A full reseal sorts it.
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. The bead needs to be tidy and fully bonded.
How we quote for glazing silicone
For a quick quote, just ask. The main things that affect it are:
- Which sealant suits the joint
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- The address or postcode of the job
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Beckenham homes and the weather
With historic houses such as Bromley Palace (about 2.1 miles east) nearby, there’s older building stock in the area around Beckenham as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Beckenham is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Harris Primary Academy Beckenham Green, its window and door frames need their mastic kept sound, just like a home’s.

- A quick top-up bead that didn’t last
- Failed joints on frameless glass

Common questions in Beckenham
Do you work for landlords with property near Beckenham Junction station?
Yes. We work for landlords and agents as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Is Beckenham in your area for glazing silicone?
Yes. Our work covers London and the South East, and Beckenham is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you replace a misted double-glazed unit?
Glass replacement isn’t our trade. We look after the sealant joints, and we will tell you if a unit looks like it has failed.
Do you reseal glass shower screens?
Yes. We remove the old silicone carefully, and the joints are cleaned and resealed.
Are you insured?
Yes. Full insurance covers our work.
