About our expansion joint sealing in Kencot
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load, so the right filler or sealant for the traffic and movement matters. We’ll tell you if the edges need repairing before sealing, and phased work keeps areas in use. If you’re dealing with car park joints leaking onto vehicles below and debris jammed in movement joints, we can help. Looking for mastic applicators who cover Kencot? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
In and around smaller places like Kencot, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Questions about Kencot
Can you take on a job at a hospital such as Longworth Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Do you cover business parks and estates near Kencot, such as Carterton South Industrial Estate?
Yes, sites like Carterton South Industrial Estate are within our area, along with the rest of Kencot. Photos and a short description are enough for a first look.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Is Kencot in your area?
Yes. Kencot is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, give us a call on 01277 525 020 or use the quote form.
Do you use silicone or polyurethane in movement joints?
The right product depends on the joint. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints, and the specification has the final say.
Do you reseal car park expansion joints?
Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Leaks coming from the membrane rather than the joint seal
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think before you book.

Diagnose, treat, sign off
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Kencot are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
- Tell us what induction or permit system the site runs

Why act early in Kencot
Some quotes just add sealant over the old bead. A bead over the old seal can’t bond or flex and soon lets go. We cut out the old seal and prepare the faces every time. Halls, stores and units around places like Kencot may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

How the job changes by surface
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies before the bead goes in.
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.
Common problems we fix in Kencot
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way.
Typical triggers for a call:
- Damp inside where a wall movement joint has failed
- Car park joints leaking onto vehicles below
- Joints where the bead has lost adhesion
- Arrises breaking up along floor joints
For an occupier at a site such as Carterton South Industrial Estate, which lies north-east of Kencot, the joints at loading doors and dock levellers typically see the hardest wear.

Doing it in-house
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.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Where floor joints take the most wear near Kencot
Kencot sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints. The 3 miles around Kencot take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Schools such as St Peter's Church of England School have movement joints in their walls and floors that are easy to overlook. Large sites such as Longworth Hospital (5.9 miles south of Kencot) have car parks, service roads and long elevations with movement joints in brick and panels.
