What happens if it’s left?
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open without shutting the whole car park. We agree phasing with you before work starts. Halls, stores and units around places like Holyport may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Expansion joint sealing in Holyport, done properly
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. We will tell you if the edges need repairing before sealing and phasing can keep areas working. We work on podiums and floor movement joints, blockwork control joints and car park decks and ramps, and the usual reasons a site gets in touch are damp inside where a wall movement joint has failed and movement joints with split or torn sealant. A specialist sealant contractor works differently from a general builder: in Holyport, that means joint design, primers and backing rod as standard.
For a site near Holyport, measurements and photos up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Common questions from Holyport clients
Can you work on a hospital site such as St Mark's Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you cover business parks and estates near Holyport, such as Trade Park?
Yes. We cover Holyport and the area around it, including industrial estates, business parks and retail parks such as Trade Park. Photos and a short description are enough for a first look.
Can you work on car park ramps and decks?
Yes, we do. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed, and we will tell you if any edges need repairing first.
Can you work while the building is occupied?
Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.
What’s the difference between an expansion joint and a movement joint?
It’s a deliberate gap that lets the structure move without cracking. Many people call it an expansion joint and both need a flexible seal.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Slabs, ramps and loading bays in Holyport
At least three named trading, business or retail sites lie within about 3 miles of Holyport. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. At about 27 miles from central London, Holyport is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London.
For an estate such as St Mark's Hospital, 2.5 miles to the north-west of Holyport, the joints in ramps, decks and long building elevations all need attention over time. Phasing is what makes joint work possible on busy sites such as Priors Way Industrial Estate (0.6 miles north-east of Holyport): one bay, aisle or car park row at a time. Estates like Trade Park (0.6 miles north-east of Holyport) combine warehouse slabs, yards and loading bays, all with joints under wheels.

On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Holyport, we aim to finish in one visit, so we ask for photos and rough sizes first. 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.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- 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.
Getting the site ready
- Tell staff and tenants when we will be in
- Tell us your opening times and when work is allowed
- Make sure the joints can be reached
Getting a fixed quote
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to speak to us on 01277 525 020 or send photos by email with what you know.
Advice
What sets the cost
To price the job, we consider:
- How accessible the joints are
- Travel to remote or island sites
- Joint width, depth and condition
- The total length or number of joints
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Details that help us quote
A few photos plus some basic facts will normally do. Please tell us:
- What the building is and how it’s used
- Asbestos survey details if the building is older
- When you need the work done
- Photos of the joints, close up and from further back
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email the details over.
Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

How the job changes by surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
