Facade sealing in Downend
A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. If you are dealing with cladding panel joints that have opened up and new sealant peeling off old mastic, we can put it right, on stone and brick facade joints, cladding panel joints and perimeter joints where frames meet the structure alike. One point of contact handles commercial sealant work in Downend from the first photos to the final walk-round, for single jobs and planned programmes alike.
In the countryside around places like Downend, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

- Joints too narrow for the movement they take, which need redesign
- Replacing glass or failed glazing units

Leave it or put it right?
Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Around Downend, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Common questions from Downend clients
Would you work within a site like Orchard Private Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is a smaller place like Downend outside your area?
Not at all. Downend is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you replace windows or glass?
No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters.
Do you run new sealant over the existing bead?
No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we’ll set out a timescale with the quote.
Do you use silicone for external joints?
The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them, and we work to what is specified.
Sites and facades in and around Downend
Downend sits in one of the drier corners of the country, the South East. 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.
When units on a site such as New Barn Industrial Park (to the south-west of Downend) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. School extensions, at buildings such as Medina College, typically run to the summer holidays, mastic included.

Signs you need facade sealing in Downend
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained and tears as the joint moves.
If one of these sounds familiar, it’s time for a closer look:
- Weathered facade joints that have lost their grip
- Perimeter joints where frames meet the structure
- Draughts around frames and panels
- Sealant pulling away from frames or panels
Projects at colleges like HTP Apprenticeship College (2.4 miles west of Downend) tend to run to term dates, so the mastic is planned tightly.
