Expansion joint sealing in Silchester, done properly
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on blockwork control joints, brickwork movement joints and precast concrete panel joints, and what we’re called in for most is leaks through car park deck joints onto the level below and expansion joints filled with dirt and stones. Most enquiries from Silchester start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In and around smaller places like Silchester, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Expansion joint sealing in Silchester: the local picture
Rainfall across the South East, Silchester included, is lower than in many parts of the UK. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints. Central London is about 45 miles from Silchester. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.
In a school such as Silchester Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Sites like Basingstoke and North Hampshire Hospital (to the south of Silchester) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Questions about Silchester
Is a hospital such as Basingstoke and North Hampshire Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is a smaller place like Silchester outside your area?
Not at all. Silchester is within our area. 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.
What sealant do you use in movement joints?
The right product depends on the joint. Facades often take a low-modulus silicone; floors and decks typically need a polyurethane, and the specification has the final say.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Why has the sealant in our expansion joints split?
The way it has failed usually tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Do you need expansion joint sealing in Silchester?
Some joints were never sealed with the right product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600.
Common reasons buildings call us in:
- Previous reseals laid over old sealant
- Debris jammed in movement joints
- Water dripping through deck or ramp joints
- Movement joints with split or torn sealant
Estates like Stacey Industrial Park, 1.2 miles to the west of Silchester, combine warehouse slabs, yards and loading bays, all with joints under wheels.
Questions to ask before you book

Why act early in Silchester
Resealing is usually the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we’ll tell you they need repairing first. Older rural buildings around Silchester move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

What affects the price in Silchester
Quotes vary with the job. It mainly depends on:
- Access and working height
- Phasing around occupants
- The size and state of each joint
- Specialist products, such as fire-rated or hygienic sealants
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
From enquiry to sign-off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. If others near Silchester need work, visits can be combined. You’ll have a fixed quote before work starts.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
What we need from you
- For older buildings, check the asbestos register before work
- Confirm the product named in the specification
- Make sure the joints can be reached

Advice
What the job involves on each surface
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability, and we will confirm the colours available for the specified product.
