Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Ask fit-out and M&E contractors to report any sealant they disturb
- Report cracked or peeling sealant early
- Brief cleaning contractors to avoid scourers and blades on sealant
- On pre-2000 buildings, share the asbestos information before work starts
We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.
Sealant installed at the same time usually fails in sequence. The first failures are often a warning about the rest so the whole run is worth inspecting. We’ll tell you which sealant joints need doing first and which can wait.
Sealant specialists in Cumnor
On a commercial site, sealant turns up in more places than people expect: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Outside, it closes facade joints, frame perimeters and movement joints against the weather. We deal with internal and external sealant joints alike, matching the sealant to the location instead of using one product throughout. We work on movement joints in walls and floors, floor and threshold joints and washrooms and tea points, and the usual reasons a site gets in touch are movement joints packed with grit and debris and a top-up bead over failed sealant, now lifting. A single leaking joint is often how a building in Cumnor first comes to us: we look at the rest while we’re there and tell you what we find.
A lot of what we do in Cumnor is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.
Work in smaller places such as Cumnor tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?
Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next, and the bill then involves other trades. Resealing while only the sealant has failed keeps the job small. Older rural buildings around Cumnor move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

What else we do in Cumnor
What we are called out for in Cumnor
The wrong sealant in the wrong place is a common cause of early failure. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed will all fail early. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason, and many specifications refer to it.
Typical triggers for a call:
- Hardened, chalky sealant on south-facing or exposed elevations
- Window and door perimeter joints that have cracked open
- Layers of sealant, all of them failing
- Untidy joints in a reception, shop floor or lobby
Sites a few miles apart, such as Wootton Business Park and West Way Shopping Centre, can share one programme and one point of contact.
Before you book anyone
- How they’ll work around occupants
- How long is the guarantee, and what does it include?
- Proof of insurance
- The named product and why it was chosen
When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Walls or slabs moving more than any sealant can take
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Water from a services leak rather than a joint
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
Joints and surfaces we work on
- Kitchen worktops and splashbacks
- Window and door perimeters
- Washrooms and tea points
- Floor and threshold joints
- External facade joints
- Movement joints in walls and floors
What sets the cost
Quotes vary with the job. It mainly depends on:
- The site’s rules and procedures
- Any access equipment needed
- The product specified
- How much existing material needs removing
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- Rough lengths or quantities, or drawings if you have them
- Whether the building will be occupied during the work
- Any dates the work must fit around
- The asbestos register, for older buildings
To get a fixed quote, speak to us on 01277 525 020 or email the details over, telling us the site location and the nature of the job. Our quote form is another easy route.

Advice
Questions about Cumnor
Is Cumnor too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you offer colour-matched sealant for buildings in Cumnor?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photographs and we’ll confirm what’s available for the product.
Is it OK to apply fresh sealant over existing beads?
Every failed bead is cut out completely. New sealant can’t grip the old bead, so laying over it never lasts.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Do you check for asbestos before removing sealant?
On older buildings, our first request is the asbestos survey. Managing asbestos is the dutyholder’s responsibility, and we don’t remove asbestos-containing materials.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you supply RAMS and insurance details?
Let us know your requirements when you ask for a price. For older buildings we will ask for the asbestos register, plus your site induction rules.
