Expansion joint sealing for commercial buildings in Havant
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors for buildings in Havant. If you have leaks through car park deck joints onto the level below and water getting into the wall through a failed joint, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Havant is the same: the right product in a properly prepared joint.
In a town the size of Havant, floor joints are mostly in industrial and trade units, supermarkets and car parks. Smaller units can’t stop work for long, so we plan around the occupier’s hours.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Havant: questions and answers
Our building in Havant is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can you work at a site such as Central Retail Park, by Havant?
Yes. Our area takes in Havant and its surroundings, with estates and business parks such as Central Retail Park included. A few photos and the unit address let us price the work.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
What exactly is a movement joint?
The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading, and the seal across it keeps water and debris out.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
What timescale should we allow for resealing expansion joints?
It usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Timings are set out in the quote, including any phasing.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, let us know and we will send them with the quote.
How the job changes by 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.
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in.
What happens if it’s left?
Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open, compared with a full closure. Tell us what has to stay open and we will plan around it. For businesses and landlords in Havant, a tidy, sound joint also matters for appearance. Renewing it keeps the building looking cared for.
A quote for movement joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

From enquiry to sign-off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most work in Havant is one building at a time: a school, a unit, an office or a block. Your photographs, drawings or a site visit come first, followed by a fixed quote.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Agree which areas must stay open
- Send any specification or drawings in advance
- Move anything stored against the joints
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
Advice
When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Crumbling edges that would give a new bead nothing sound to grip
- Cracking or settlement that calls for an engineer’s assessment
If you are not sure, just call the office on 01277 525 020 or send photos by email and we will give you a straight answer.

Where floor joints take the most wear near Havant
Havant lies within about 2 miles of the sea. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.
Another example is Solent Retail Park, which lies south of Havant, where floors and yards would be done in stages around the occupiers. For a school such as Trosnant Infant School, playground and building joints can be done in the holidays.
