About our facade sealing in Temple Dinsley
We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds, using sealants classified for facade or glazing use. We work on stone and brick facade joints, cladding panel joints and window and door perimeters, and what we are called in for most is cladding panel joints that have opened up and old perimeter mastic that has dried out. For commercial sealant work in Temple Dinsley, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around smaller places like Temple Dinsley, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Work on the window or framing system itself
- Cracked or spalling substrates that need repair before sealing
- Providing access systems for the work
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Different surfaces, different methods
Cladding panel joints
On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch.
Do you need facade sealing in Temple Dinsley?
Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.
Any of the following is a good reason to get the joints checked over:
- Discoloured or dirty facade joints
- Perimeter sealant that has split or peeled away
- Gaps between rainscreen or cladding panels
- New sealant peeling off old mastic
Hospital estates such as Lister Hospital, 2.9 miles to the north-east of Temple Dinsley, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Contractors’ notes for Temple Dinsley
The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Temple Dinsley is about 29 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.
New units and refits on sites such as Horizon Technology Park (3 miles east of Temple Dinsley) need their panel and perimeter joints sealed to the specification. School extensions, at buildings such as Preston Primary School, typically run to the summer holidays, mastic included.
