How we handle facade sealing in Potten End
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. If you’re dealing with cold air coming in at window perimeters and new sealant peeling off old mastic, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Potten End it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Conversions of older rural buildings near smaller places such as Potten End bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What we can’t put right

- Cracked or spalling substrates that need repair before sealing
- Movement beyond what any sealant can handle
If in doubt, call 01277 525 020 or email the details over and we’ll say what we think.

Sites and facades in and around Potten End
Potten End sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. Potten End lies roughly 26 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.
For contractors refurbishing units at places like River Park Industrial Estate, which lies west of Potten End, the mastic covers cladding panels, roller-door and window perimeters. Projects at schools like Potten End CofE Primary School work to term dates, so mastic is programmed tightly.

When to call us in Potten End
Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building.
Any of the following is a good reason to get the joints checked over:
- Sealant pulling away from frames or panels
- New sealant peeling off old mastic
- Staining on stone next to old sealant
- Old perimeter mastic that has dried out
Further education sites such as West Herts College (2.4 miles south-east of Potten End) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Is any job too small?

Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Should we check old sealant for asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.
What type of sealant goes on window perimeters?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, depending on the substrate and the specification.
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Record the product and colour used on each elevation
- Share access with other external trades
- Insist on a full cut-out when joints are renewed
- Walk the elevations once or twice a year
Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly with a compatible product.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.
Different surfaces, different methods
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them to the correct depth.
From enquiry to sign-off
Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Potten End are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Preparing the site
- Share the asbestos register for older buildings
- Move anything stored against the joints
- Explain the parking and delivery arrangements

What sets the cost
Before we quote, we look at:
- Any access equipment needed
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Send us:
- What the building is and how it’s used
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
- Specification clauses that apply
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
