How the job changes by surface
Cladding panel joints
Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.
Perimeter joints at frames and structure
Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed using a sealant classified for that use.
About our facade sealing in Hassell Street
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. Most enquiries involve sealant pulling away from frames or panels and cold air coming in at window perimeters, across perimeter joints where frames meet the structure, stone and brick facade joints and shopfront frames. A single leaking joint is often how a building in Hassell Street first comes to us: we look at the rest while we are there and tell you what we find.
In the countryside around places like Hassell Street, 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.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Common questions from Hassell Street clients
Can you keep pace with our programme in Hassell Street?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you work on a hospital site such as William Harvey Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
Should we check old sealant for asbestos?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. Suspect material is left alone until it has been tested.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Can you look at water coming in around a frame?
Yes. We check the sealant joints and report what we find before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
Do you provide access for facade work?
We agree access with the client at the start. Tell us about access: existing scaffold, what you are arranging and any site restrictions.
Mastic packages on Hassell Street sites
Rainfall across the South East, Hassell Street included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. Central London is about 52 miles from Hassell Street. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
Extensions at sites like William Harvey Hospital, 4.2 miles to the south-west of Hassell Street, normally sit beside working departments, and the mastic follows strict access rules. School extensions, at buildings such as Wye School, typically run to the summer holidays, mastic included.

Why act early in Hassell Street
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. One visit to deal with every failing joint makes more sense than several trips to a place like Hassell Street, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Related advice
After the work
A few simple habits keep the new joints working:
- Add perimeter sealant to planned maintenance checks
- Keep sills, gutters and drainage paths clear
- Brief window cleaners about newly sealed joints
- Check the asbestos register before old mastic is disturbed
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.
