Expansion joint sealing in Avisford
Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on cladding panel joints, podiums and floor movement joints and brickwork movement joints, and the failures we’re asked to look at most are joints packed with grit and debris and water dripping through deck or ramp joints. Facilities teams, main contractors and managing agents in Avisford tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In and around smaller places like Avisford, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Diagnose, treat, sign off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. Smaller jobs around Avisford can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Preparing the site
- Tell us what induction or permit system the site runs
- Send any specification or drawings in advance
- Point out any areas we must not close

Common questions from Avisford clients
Is Avisford too small for you to travel to?
No. Places such as Avisford are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Do you cover business parks and estates near Avisford, such as Tokar Industrial Park?
Yes. We cover Avisford and the area around it, including industrial estates, business parks and retail parks such as Tokar Industrial Park. A few photographs and the unit address let us price the work.
Do you guarantee expansion joint work?
It’s backed by our 12-month guarantee. Tell us right away if a joint we sealed gives trouble in that time.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Can a joint be sealed if the edges are broken?
Broken arrises have to be put right before resealing. A bead on a broken edge soon lets go.
Common problems we fix in Avisford
The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.
Site and facilities staff are often the first to spot these:
- Joints where the bead has lost adhesion
- Expansion joints split through the centre of the bead
- Weathered movement joint sealant that no longer flexes
- Water getting into the wall through a failed joint
A campus such as University of Chichester (Bognor Campus) (4.7 miles south-west of Avisford) has long runs of movement joint in its buildings, decks and paving.
What your quote should include
- Their pre-qualification and accreditations
- The terms of the workmanship guarantee
- Whether primer will be used where the manufacturer specifies it
- What level of public liability insurance do they hold?
Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Avisford can sit alongside others in a wider programme.
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.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Put movement joints on the planned maintenance inspection round
- Act on the first tear or lifting edge rather than waiting
- Keep scrapers and ploughs from dragging across joint sealant
- Look over external and deck joints after a hard winter
Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint and we will tell you when each bay or area can reopen. Barriers left in place until then protect the finish.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors, well after the seal first opened. Catching it early keeps the water outside.
What affects the price in Avisford
The price varies from site to site. Expect it to depend on:
- Distance, for remote addresses
- How accessible the joints are
- Joint width, depth and condition
- How much there is to seal
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- Any specification or named product
- Whether an asbestos survey exists
- Anything awkward about access or site hours
- What the building is and how it’s used
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Why act early in Avisford
Resealing is usually the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. Older rural buildings around Avisford move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
