Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Quoting for work in Headley Down
Each job is priced on its own details. The main factors are:
- Distance, for remote addresses
- How much there is to seal
- How accessible the joints are
- Backing rod, priming and other preparation
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What to include in your enquiry
However big the job, the same details help:
- Any dates the work must fit around
- The type of building and who uses it
- Anything awkward about access or site hours
- Asbestos survey details if the building is older
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Do you need facade sealing in Headley Down?
Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.
Any of the following is a good reason to get the joints checked over:
- Cladding panel joints that have opened up
- Weathered facade joints that have lost their grip
- Failed seals around shopfront and entrance frames
- Perimeter sealant that has split or peeled away
On a healthcare site such as Chase Hospital, which lies west of Headley Down, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What to look for in a quote
- What the guarantee covers, and for how long
- Will RAMS and insurance details be available?
- Is the sealant right for the movement and the substrate?
- Will failed sealant be removed rather than covered?
Our process
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. What matters most for a job in Headley Down is a clear list of what needs doing, so send photographs of each area. You’ll then get a fixed price for the work.
- 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 is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Getting the site ready
- Confirm the product named in the specification
- Tell us your opening times and when work is allowed
- Warn occupants and staff about the work
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Related advice
Leave it or put it right?
Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Pricing facade joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Common questions from Headley Down clients
Is hospital work, at somewhere like Chase Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Headley Down off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do we need an asbestos check before resealing?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
How many days will you need on site?
It depends on the scope, though a typical visit typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we will set out a timescale with the quote.
Facade sealing in Headley Down: the local picture
Rainfall across the South East, Headley Down included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. Central London is about 40 miles from Headley Down. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.
Recladding or extending a unit at a site like Passfield Industrial Estate (to the south-west of Headley Down) brings panel joints and frame perimeters into the programme. Projects at schools like The Holme Church of England Primary School work to term dates, so mastic is programmed tightly.
