Why act early in Westerham
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. We will flag where edges need repair before sealing. In a smaller place such as Westerham, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

FAQs: Westerham
Must our site in Westerham stop work while the joints are done?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we will plan from there.
Would you work within a site like Tandridge Priory?
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.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
What causes movement joint sealant to fail?
Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing.
What happens if it rains on the day?
A wet joint can’t be sealed properly. We agree a revised date with you.
Are expansion joints and movement joints the same thing?
Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Building owners, agents and FMs in Westerham
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Advice
When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Aftercare for building managers
For the best life from the joints:
- Include every elevation and deck joint in periodic inspections
- Avoid parking heavy plant or pallets on joint lines
- Treat a small split as a warning, not a cosmetic issue
- Clear dirt from joint lines during routine cleaning
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file so future maintenance isn’t guesswork.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Sealing the joint promptly stops it at source.
Warehouse floors and decks around Westerham
Westerham lies roughly 17 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Westerham sits in one of the drier corners of the country, the South East. 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.
For an estate such as Tandridge Priory (2.2 miles south-west of Westerham), the joints in ramps, decks and long building elevations all need attention over time. In and around Westerham, the right filler or sealant for each joint depends on the traffic and the movement it takes.

How the job changes by surface
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen in a colour confirmed for that product.
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler.
