About our expansion joint sealing in Offham
Every structure moves a little, all the time: 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 on sites in Offham. Site teams most often ask us about layers of sealant in a movement joint and water dripping through deck or ramp joints, on car park decks and ramps, podiums and floor movement joints and precast concrete panel joints. Searching for sealant specialists in Offham? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

What else we do in Offham
On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Jobs in and around smaller places like Offham are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Tell us which areas need to stay in use
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints

Your questions answered
Is hospital work, at somewhere like Lewes Victoria Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is a smaller place like Offham outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
What if the joint edges are damaged?
Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we’ll say so when we quote.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member.
Are expansion joints and movement joints the same thing?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What sets the cost
To price the job, we consider:
- The total length or number of joints
- Induction, permit and paperwork requirements
- Working within restricted access windows
- Specialist products, such as fire-rated or hygienic sealants
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- The type of building and who uses it
- The product your specification calls for
- The postcode of the building
- Photos of the joints, close up and from further back
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Warehouse floors and decks around Offham
At least three named trading, business or retail sites lie within about 3 miles of Offham. Their warehouses, yards and car parks are exactly where joints take the most punishment. Offham is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.
Estates like Riverside Industrial Estate, 1.3 miles to the south-east of Offham, combine warehouse slabs, yards and loading bays, all with joints under wheels. Large sites such as Lewes Victoria Hospital, 1.2 miles to the south of Offham, have car parks, service roads and long elevations with movement joints in brick and panels. University campuses such as University of Sussex, 3.7 miles south-west of Offham, have car parks, paved walkways and building elevations with movement joints.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Cracking or settlement that calls for an engineer’s assessment
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Damaged metal nosings or cover plates over a joint

Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
What the job involves on each surface
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 and check the edges for soundness as we go.
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies.
