Expansion joint sealing in Houghton, done properly
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Houghton. If you have expansion joints filled with dirt and stones and water getting into the wall through a failed joint, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Houghton it comes down to the same thing: the right product in a properly prepared joint.
In and around smaller places like Houghton, 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.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Common questions from Houghton clients
Do we have to stop operations in Houghton while the joints are sealed?
Rarely. Work is phased around your operations. The phasing plan comes with the quote.
Is Houghton off your patch?
No. Places such as Houghton are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
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.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Do you use silicone or polyurethane in movement joints?
It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks normally need a polyurethane.
Are you insured?
Yes. We are fully insured, including public liability cover.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Slabs, ramps and loading bays in Houghton
Rainfall across the South East, Houghton included, is lower than in many parts of the UK. External joints still wait for dry conditions, while winter salting gets into any joint left open. At about 68 miles from central London, Houghton is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds.
For a school such as Test Valley School, playground and building joints can be done in the holidays.

Common problems we fix in Houghton
When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, usually means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way, so we check width and movement before quoting.
Any of the following is a good reason to get the joints checked over:
- Expansion joints split through the centre of the bead
- Arrises breaking up along floor joints
- Joints where the bead has lost adhesion
- Leaks through car park deck joints onto the level below
Around Houghton, each joint gets a filler or sealant matched to what crosses it and how much it moves.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
- How the existing material will be dealt with
- What the guarantee covers, and for how long
Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. For work around Houghton, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We assess the joints on site or from photos, noting widths and how each has failed.
- 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.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

- Move anything stored against the joints

After the work
Problems stay small when the joints are checked regularly. In particular:
- Report split or peeling joint sealant early
- Check joints after long freezing spells
- Note which joints were done, when, and with what
- Keep traffic off new joints until the cure time is up
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in and long before edges start to break. Should you spot a problem, you can give us a call on 01277 525 020 or email a schedule or drawings and send a picture.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors. Catching it early keeps the water outside.
What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Induction, permit and paperwork requirements
- The total length or number of joints
- Backing rod, priming and other preparation
- The product specified
Pricing movement joints depends on quantities, condition and access, and any specification that applies. Call for a quote.
What we need to price the job
However big the job, the same details help:
- Access details, including height
- Drawings or a marked-up plan, if available
- Asbestos survey details if the building is older
- Any specification or named product
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or phone 01277 525 020 or send photos by email to discuss it first.
Why deal with it now?
A torn seal left alone typically gets worse. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Around Houghton, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Surface by surface
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.
Concrete and precast panel joints
Precast and concrete panel joints move daily. The sealant needs the right movement capability and a controlled depth.
