Expansion joint sealing in Sandford
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
FAQs: Sandford
Our building in Sandford 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. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Do you take on work at healthcare sites like Arthur Webster Memorial Hospital for Children?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
How long will the joint resealing take?
Expect a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. We will confirm when each area can be used again.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure.
Can a joint be sealed if the edges are broken?
Spalled edges need repairing before a new seal will last. Sealing over them leads to early failure.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Expansion joint sealing in Sandford, done properly
Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in Sandford. Most enquiries involve water getting into the wall through a failed joint and torn sealant in brick or block movement joints, on precast concrete panel joints, blockwork control joints and cladding panel joints. Searching for sealant specialists in Sandford? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around smaller places such as Sandford, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Looking after the joints
For the best life from the joints:
- Keep traffic off new joints until the cure time is up
- Check joints after long freezing spells
- Raise snow-clearing blades over deck joints where possible
- Avoid parking heavy plant or pallets on joint lines
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in and long before edges start to break. If anything looks wrong, call 01277 525 020 or email a schedule or drawings with photographs.
Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load. Keeping the seal sound avoids all of that.
Traffic, movement and joints around Sandford
Sandford lies within about 3 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 it pays to keep them sealed. Rainfall across the South East, Sandford included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.
Across sites such as Branstone Business Park, 1.5 miles north-east of Sandford, floor and movement joints can be sealed in phases so units keep working. Sites like Arthur Webster Memorial Hospital for Children, 2.5 miles east of Sandford, carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Sandford is about 5 miles south-east of Newport, in the Isle of Wight. Anywhere in PO38, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 125 places in the Isle of Wight, from busy centres to rural villages. Sites around Portsmouth have their own page, about 14 miles away.
Commercial sites across PO38 are covered for movement joints. If your site is on Shanklin Road and Redhill Lane or close by, we can quote for movement joints. Nearby places we also cover include Whiteley Bank (1 mile east), Godshill (1 mile west), Princelett (1 mile north-east), Wroxall (1 mile south-east) and Hale Common (1 mile north). Further afield, our area takes in Newport (5 miles north-west), Ryde (7 miles north-east), Cowes (9 miles north), Sandown (4 miles north-east), Shanklin (3 miles east) and Ventnor (3 miles south-east). Where a site is remote or on an island, we plan travel and materials carefully, so include the location in your enquiry.
Local landmarks in Sandford
Locally, jobs take us to sites close to The Griffin Public House. The closest station to Sandford is Shanklin station, about 2.5 miles east of the centre.

Our process
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. If others near Sandford need work, visits can be combined. You’ll have a fixed quote before work starts.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- 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.
- 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.
Getting the site ready

Advice
What the job involves on each surface
Brickwork and blockwork joints
Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it.
Cladding panel joints
We confirm what access is in place before pricing. Close-up photographs help us judge the joints.

Honest limits
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Leaks coming from the membrane rather than the joint seal
- Changing the joint layout or spacing of a structure
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think before you book.

What we are called out for in Sandford
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.
Look out for the following:
- Car park joints leaking onto vehicles below
- Previous reseals laid over old sealant
- Hardened, cracked sealant on exposed facades
- Expansion joints split through the centre of the bead
For a school such as Godshill Primary School, playground and building joints can be done in the holidays.
