Expansion joint sealing in Over Wallop, done properly
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. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Over Wallop. We work on podiums and floor movement joints, precast concrete panel joints and brickwork movement joints, and what we are called in for most is damp inside where a wall movement joint has failed and car park joints leaking onto vehicles below. Most enquiries from Over Wallop start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For a site near Over Wallop, measurements and photos up front mean one trip where possible, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Floors, slabs and movement joints in Over Wallop

Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day.

How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Over Wallop, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- 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.
- 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.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Warn occupants and staff about the work
- Send any specification or drawings in advance

Your questions answered
Is Over Wallop too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Which documents can you supply for work in Over Wallop?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Do you reseal car park expansion joints?
Yes, we do. These joints take wheels, salt and water, so product choice matters and broken edges are flagged before sealing.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Owners, agents and contractors
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Over Wallop can sit alongside others in a wider programme.
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
What the job involves on each surface
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement.
Cladding panel joints
We confirm what access is in place before pricing. Photos taken near the joints help us price accurately or a site visit fills the gaps.
Quoting for work in Over Wallop
These are the things that shape the price:
- Whether the work must be split into stages
- Location, for remote and island sites
- Quantities, in metres or numbers
- How accessible the joints are
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
What to include in your enquiry
A good diagnosis starts with the right details. Tell us:
- Where the site is, with the postcode
- Whether the building will be occupied during the work
- Anything awkward about access or site hours
- Your programme or deadline
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Signs you need expansion joint sealing in Over Wallop
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
What tends to prompt an enquiry:
- Chipped joint edges on forklift routes
- Expansion joints split through the centre of the bead
- Leaks through car park deck joints onto the level below
- Brittle, chalky sealant on external joints
In a school such as Wallop Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
Questions to ask before you book
- What site paperwork they can supply
- Their public liability cover
- What the guarantee covers, and for how long
- Will CSCS-carded applicators be on site?
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Waterproofing layers buried beneath the sealant
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If in doubt, phone 01277 525 020 or use the quote form and we will say what we think before you book.
