About our facade sealing in Radnage
Managing agents and owners in Radnage ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. If you have weathered facade joints that have lost their grip and cladding panel joints that have opened up, we can help, on perimeter joints where frames meet the structure, window and door perimeters and shopfront frames alike. A single leaking joint is often how a building in Radnage first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Conversions of older rural buildings near smaller places such as Radnage bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
A 12-month guarantee applies to all our work in Buckinghamshire. Should something we installed fail, give us a call on 01277 525 020 or email the details over and we will come back to it.

How the job changes by surface
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification with a product suited to glazing perimeters.
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather.
What else we do in Radnage
What happens if it’s left?
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. Halls, stores and units around places like Radnage may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

General trades versus a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Which sealant do you use on facades?

New build and refits around Radnage
Central London is about 35 miles from Radnage. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Radnage is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
When a school such as Radnage Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Historic houses such as West Wycombe Park House (3.2 miles south-east of Radnage) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Radnage is about 6 miles north-west of High Wycombe, in Buckinghamshire. If you’re looking for facade sealing in Radnage, we can help, as we do across Buckinghamshire. Radnage is one of 308 places in Buckinghamshire on our list. There’s a separate page for Reading, about 16 miles away.

When to call us in Radnage
Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead.
Any of the following is a good reason to get the joints checked over:
- Damp patches beside frames after rain
- Facade joints cracked through the middle
- Hard, chalky sealant that no longer flexes
- Patch repairs that keep failing
Recladding or extending a unit at a site like Crownfield Industrial Estate (1.8 miles north-east of Radnage) brings panel joints and frame perimeters into the programme.
