We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Merstham. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Facade sealing for commercial buildings in Merstham
Managing agents and owners in Merstham ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on stone and brick facade joints, shopfront frames and cladding panel joints, and what we’re called in for most is discoloured or dirty facade joints and failed seals around shopfront and entrance frames. A single leaking joint is often how a building in Merstham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Sites around smaller places like Merstham can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.
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.

Surface by surface
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.
Brick and stone facades
Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.

Cost factors for facade joints
What shapes the price:
- The size and state of each joint
- How much there is to seal
- Whether the work must be split into stages
- Which sealant the job calls for
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Details that help us quote
Good information means a firmer quote. Helpful details to send:
- Clear photos of the problem areas
- The postcode of the building
- The type of building and who uses it
- Anything awkward about access or site hours
For a fixed quote, phone 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. Our quote form is another easy route.
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Never let anyone seal over old sealant
- Report water ingress at frames as soon as it shows
- Keep pressure washers away from fresh sealant
- Note when each elevation was last resealed
Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed instead of soaking the joints.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
Common questions from Merstham clients
Is Merstham too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work around term dates at a campus such as Coulsdon Sixth Form College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, which many sites require.
Do we need an asbestos check before resealing?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member.
Can staff carry on working while you are here?
In the majority of cases, yes. We phase the work so most of the building stays in use.
Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Merstham can be grouped with others nearby. You’ll have a fixed quote before work starts.

Leave it or put it right?
Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. Converted and older buildings near places like Merstham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Facade sealing in Merstham: the local picture
Central London is about 16 miles from Merstham. 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. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
Recladding or extending a unit at a site like Brewerstreet Dairy Business Park, 2.4 miles to the south-east of Merstham, brings panel joints and frame perimeters into the programme. Projects at schools like Merstham Primary School work to term dates, so mastic is programmed tightly. For a contractor working at a hospital such as North Downs Hospital, 2.9 miles to the east of Merstham, perimeter and facade sealing is planned around patients and deliveries.
