About our facade sealing in Chale
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, often at around 2:1 width to depth, as the manufacturer advises. If you’re dealing with failed seals around shopfront and entrance frames and leaks at window and door perimeters, we can help, on window and door perimeters, stone and brick facade joints and coping and flashing joints alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Chale it comes down to the same thing: the right product in a properly prepared joint.
For a site near Chale, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Chale, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
What we need from you
- Move anything stored against the joints
- Arrange parking or a loading space
- Flag any permit to work we will need

Why deal with it now?
Topping up a failed joint normally buys very little time. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. Around Chale, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Different surfaces, different methods
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and we’ll mention any edges that need repair.
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints, tooled to shed water.
Keeping the joints sound
For the best life from the joints:
- Record the product and colour used on each elevation
- Add perimeter sealant to planned maintenance checks
- Share access with other external trades
- Check the asbestos register before old mastic is disturbed
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Cracked or spalling substrates that need repair before sealing
- Replacing glass or failed glazing units
If you’re not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Surfaces we seal
- Window and door perimeters

New build and refits around Chale
The sea is no more than about 1 mile from Chale. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
Historic houses such as Wolverton Manor, 3.4 miles to the north-west of Chale, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Signs you need facade sealing in Chale
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.
Any of the following is a good reason to get the joints checked over:
- Previous reseals run over old sealant
- Old perimeter mastic that has dried out
- Draughts around frames and panels
- Facade joints cracked through the middle
Extensions at sites like Whitecroft Hospital, 5.2 miles north of Chale, usually sit beside working departments, and the mastic follows strict access rules.

Your questions answered
Is Chale too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Is hospital work, at somewhere like Whitecroft Hospital, something you do?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
How do I request a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
Is it okay to overlay old mastic?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member.
Is old mastic on our building likely to contain asbestos?
In older non-domestic buildings, old sealant 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.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
