Facade sealing in Box Hill, done properly
Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. We work on stone and brick facade joints, cladding panel joints and perimeter joints where frames meet the structure, and what we’re called in for most is perimeter sealant that has split or peeled away and previous reseals run over old sealant.

Around smaller places like Box Hill, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email drawings and photos and we’ll come back to it.

When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

From enquiry to sign-off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Rural sites near Box Hill may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Share the asbestos register for older buildings
- Flag any permit to work we will need
- Point out any areas we must not close

Advice
How the quote is worked out
Before we quote, we look at:
- Any access equipment needed
- Joint width, depth and condition
- How much existing material needs removing
- The site’s rules and procedures
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Asbestos survey details if the building is older
- Specification clauses that apply
- Where the site is, with the postcode
- Drawings or a marked-up plan, if available
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Why deal with it now?
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice. Older rural buildings around Box Hill move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Questions about Box Hill
Can you work on a hospital site such as Dorking Community Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work at a site such as Chesterfield Business Park, by Box Hill?
Yes. Estates, retail parks and business parks around Box Hill, Chesterfield Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
What type of sealant goes on window perimeters?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.
Is it okay to overlay old mastic?
No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.
What do you charge?
Every job gets its own fixed quote. For yours, phone 01277 525 020 or email us with a description of the work.
Can you find out why a window is leaking?
Yes. Photos help, and you can ring 01277 525 020 or email drawings and photos to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we’ll be honest about which it is.
Honest limits
Honesty saves time and money. New sealant won’t cure:
- Providing access systems for the work
- Joints whose design needs changing by the specifier
- Replacing glass or failed glazing units
If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Facade sealing around Box Hill: points for this area
Box Hill sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. At about 19 miles from central London, Box Hill is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
New units and refits on sites such as Chesterfield Business Park (2.3 miles east of Box Hill) need their panel and perimeter joints sealed to the specification. School extensions, at buildings such as The Ashcombe School, normally run to the summer holidays, mastic included.
Box Hill is about 2 miles north-east of Dorking, in Surrey. Box Hill sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Box Hill is one of 379 places in Surrey on our list. For work in that direction, see our London page.
If you need facade sealing in KT20, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Common problems we fix in Box Hill
Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
Common reasons buildings call us in:
- Sealant pulling away from frames or panels
- Old perimeter mastic that has dried out
- Patch repairs that keep failing
- Failed sealant on precast panel joints
Older buildings in the area around Box Hill, such as Polesden Lacey, 3.9 miles to the west of Box Hill, need care when sealed: the product has to suit soft or historic materials.
