Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When to call us in Fawley
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes.
Clients typically get in touch after noticing one or more of the following:
- Joints packed with grit and debris
- Weathered movement joint sealant that no longer flexes
- Expansion joints split through the centre of the bead
- Water getting into the wall through a failed joint
Schools such as Fawley Infant School have movement joints in their walls and floors that are easy to overlook.

How we handle expansion joint sealing in Fawley
Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. If you have chipped joint edges on forklift routes and joints where the bead has lost adhesion, we can help, on podiums and floor movement joints, blockwork control joints and brickwork movement joints alike. A single leaking joint is often how a building in Fawley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Jobs around smaller places like Fawley are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Warehouse floors and decks around Fawley
Fawley sits close to the coast, within about 1 mile. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. Fawley has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
A healthcare site such as Coldeast, 4.2 miles to the north-east of Fawley, depends on car parks, ramps and service yards whose joints take traffic all day. Another example is Hardley Industrial Estate (2.2 miles north-west of Fawley), where floors and yards would be done in stages around the occupiers.

Questions about Fawley
Do you take on work at healthcare sites like Coldeast?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Our building in Fawley is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Do you use silicone or polyurethane in movement joints?
Whatever suits the joint and the specification. We name the proposed product in the quote.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
What sets the cost
To price the job, we consider:
- How much there is to seal
- How much existing material needs removing
- The product specified
- Backing rod, priming and other preparation
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What to include in your enquiry
We can often quote from photos and a few details. Please tell us:
- Where the site is, with the postcode
- The product your specification calls for
- When you need the work done
- The type of building and who uses it
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or use the quote form.
Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. If others near Fawley need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We look at the joints, their width and how they’ve failed.
- Next, we fix a price and confirm the sealant we propose for the movement.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Each joint is inspected and handed over with our 12-month guarantee.
Preparing the site
- Let building users know which areas are affected
- Arrange parking or a loading space
- Confirm the product named in the specification

Related advice
Surface by surface
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. They take a low-modulus sealant with a movement class to suit, with backing rod setting the depth.
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it.
After the work
Once the work is signed off, a little attention goes a long way:
- Keep stones and debris out of open joint lines
- Keep product details with the building records for the next reseal
- Check joints after long freezing spells
- Inspect movement joints alongside other routine building checks
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. If anything looks wrong, speak to us on 01277 525 020 or send details through our quote form with photographs.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.
