Facade sealing for commercial buildings in Thorney
Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. If you are dealing with new sealant peeling off old mastic and hard, chalky sealant that no longer flexes, we can help, on window and door perimeters, stone and brick facade joints and shopfront frames alike.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?
Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Converted and older buildings near places like Thorney tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What you get with us
- Colours chosen to suit frames, cladding or finishes where possible

Diagnose, treat, sign off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. If others near Thorney need work, visits can be combined. You will have a fixed quote before work starts.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Share the asbestos register for older buildings
- Send your site hours and access windows
- Clear stock, furniture or equipment away from the joints

Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
How the job changes by surface
Coping and flashing joints
Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.
Sites and facades in and around Thorney
Thorney has plenty of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Thorney 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 the external programme keeps a little slack.
For contractors on a campus like Brunel University of London, which lies north of Thorney, facade and perimeter sealing has to fit around students and term dates. Work at a hotel such as Riverside Hotel, 0.9 miles to the north-east of Thorney, tends to be programmed around bookings, mastic included. Recladding or extending a unit at a site like Court Lane Industrial Estate (0.7 miles north-west of Thorney) brings panel joints and frame perimeters into the programme.

FAQs: Thorney
Can you work at a site such as Court Lane Industrial Estate, by Thorney?
Yes, sites like Court Lane Industrial Estate are within our area, along with the rest of Thorney. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Is a smaller place like Thorney outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
How do I request a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or email a schedule or drawings. Include photos or drawings if you have them.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Should we check old sealant for asbestos?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, and we will ask to see it. Suspect material is left alone until it has been tested.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
