Our process
Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Westmarsh, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- Share the asbestos register for older buildings
- Tell us what induction or permit system the site runs
- Let building users know which areas are affected

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

FAQs: Westmarsh
Is a smaller place like Westmarsh outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Will our site in Westmarsh have to close for joint sealing?
Rarely. Work is phased around your operations. The phasing plan comes with the quote.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
What happens if it rains on the day?
The joint has to be dry, and the air and surface temperature inside the product’s limits. Frost, rain and condensation on steel or concrete can hold up external work, so we plan with the forecast in mind.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
When to call us in Westmarsh
Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.
If one of these sounds familiar, it’s time for a closer look:
- Spalled or broken joint edges in floors and decks
- Layers of sealant in a movement joint
- Expansion joints filled with dirt and stones
- Damp inside where a wall movement joint has failed
Office parks like Monkton Business Centre, 2.4 miles to the north of Westmarsh, have decks, ramps and clad elevations whose joints take movement every day.
What to look for in a quote
- Will RAMS and insurance details be available?
- Who will actually carry out the work
- Their plan for phasing and protecting the area
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
What the job involves on each surface
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement, and confirm it in the quote.
Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Traffic, movement and joints around Westmarsh
Central London is about 60 miles from Westmarsh. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day. Rainfall across the South East, Westmarsh 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 winter de-icing salt on car parks and ramps works into any open joint.
For floors and slabs around Westmarsh, the product is chosen for the traffic and the movement at each joint.

Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Record the sealant used and the date in the O&M file
- Brief car park operatives to protect joint lines during winter clearance
- Treat a small split as a warning, not a cosmetic issue
- Inspect movement joints alongside other routine building checks
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears. Regular sweeping keeps joint lines clear.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.
