About our expansion joint sealing in Whitesmith
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. If you have car park joints leaking onto vehicles below and layers of sealant in a movement joint, we can help, whatever the surface. One point of contact handles commercial sealant work in Whitesmith from the first photos to the final walk-round, for single jobs and planned programmes alike.
Around smaller places such as Whitesmith, 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.
Every job we finish is backed by a 12-month workmanship guarantee, in Whitesmith as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we are called out for in Whitesmith
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.
Look out for the following:
- Torn sealant in brick or block movement joints
- Joints packed with grit and debris
- Sealant pulling off the joint face
- Hardened, cracked sealant on exposed facades
Office parks like Stone Cross Business Centre (to the south-west of Whitesmith) have decks, ramps and clad elevations whose joints take movement every day.
Questions to ask before you book
- How the joint faces will be prepared and primed
- Whether old or failed sealant will be cut out, not overlaid
- Are they CHAS accredited or on Constructionline?
- Their plan for phasing and protecting the area
What the job involves on each surface
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them, and tell you if edges need repairing first.
Podium joints
Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.
Owners, agents and contractors
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Questions about Whitesmith
Can you take on a job at a hospital such as Hellingly Hospital Railway?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work at a site such as Stone Cross Business Centre, by Whitesmith?
Yes. We cover Whitesmith and the area around it, including industrial estates, business parks and retail parks such as Stone Cross Business Centre. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
What timescale should we allow for resealing expansion joints?
It usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Cure time before reopening is confirmed on the day.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
How much does the work cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Do you work in Whitesmith?
Yes. Whitesmith is in our area and the rest of East Sussex. To discuss a job, call the office on 01277 525 020 or send photos by email.
What sets the cost
Your fixed quote is built from the real scope. It allows for:
- Whether old sealant has to be cut out first
- Joint width, depth and condition
- The site’s rules and procedures
- Access and working height
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What we need to price the job
Diagnosis starts before we arrive. Tell us:
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
- Clear photographs of the problem areas
- Anything awkward about access or site hours
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. If others near Whitesmith need work, visits can be combined. You will have a fixed quote before work starts.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Flag any permit to work we will need
- Send your site hours and access windows

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Whitesmith lies roughly 43 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. At least three named trading, business or retail sites lie within about 3 miles of Whitesmith. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
In a school such as Chiddingly Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. At places like Oakwood Business Park, 1.4 miles south-east of Whitesmith, joints are sealed a section at a time so operations carry on.

Keeping the joints sound
A few simple habits keep the new joints working:
- Keep traffic off new joints until the cure time is up
- Clear dirt from joint lines during routine cleaning
- Avoid parking heavy plant or pallets on joint lines
- Inspect movement joints alongside other routine building checks
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file so future maintenance isn’t guesswork.
Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. A sound seal keeps the joint working.
