Expansion joint sealing in Datchet
Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. If you have chipped joint edges on forklift routes and rain penetration at brick or block movement joints, we can put it right, whatever the surface. Whoever orders the work in Datchet, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Around places the size of Datchet, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Their slabs and walls still need movement joints that work.
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.

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Waterproofing layers buried beneath the sealant
- Movement on a scale no sealant is meant to absorb
- Changing the joint layout or spacing of a structure
If in doubt, call the office on 01277 525 020 or use the quote form and we will say what we think.
What we seal

How the job changes by surface
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing.

That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Datchet is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open.
Retail centres such as Slough Retail Park, 2.8 miles to the north-west of Datchet, have floors, service yards and car parks with joints under constant traffic. Campuses like Royal Holloway University (to the south of Datchet) mix old and new buildings, with movement joints wherever they meet. Across sites such as Deseronto Trading Estate, which lies north-east of Datchet, floor and movement joints can be sealed in phases so units keep working.

Why act early in Datchet
A torn seal left alone normally gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. In a smaller place such as Datchet, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

On site: what to expect
Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. If neighbouring businesses or buildings around Datchet need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- 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.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Preparing the site
- Share your working hours and any access restrictions
- Arrange parking or a loading space
- Make sure the joints can be reached
Quotes
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.

Your questions answered
Can you work on a hospital site such as Princess Margaret Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is Datchet too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Do you reseal car park expansion joints?
Yes. Let us know the opening hours and which levels or bays have to stay available and we’ll plan around them.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Can a joint be sealed if the edges are broken?
Broken arrises have to be put right before resealing, and we’ll point out where that’s the case. A bead on a broken edge soon lets go.
What guarantee do you give on joint sealing?
It’s backed by our 12-month guarantee. If a joint we sealed fails inside the 12 months, let us know.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
