FAQs: South Merstham
Can you quote for a block close to Merstham station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Can you work at a site such as Kingsfield Business Centre, by South Merstham?
Yes. Our area takes in South Merstham and its surroundings, with estates and business parks such as Kingsfield Business Centre included. Send details of the unit and the work through our quote form for a quick quote.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How long does a typical visit take?
It depends on the scope, but the work typically takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
Do you work with property factors and landlords?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.

Doing it in-house
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, which is what makes a joint last.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Quantities, in metres or numbers
- Which sealant the job calls for
- Induction, permit and paperwork requirements
- Access and working height
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you are ready.
Before you send an enquiry
Whether it’s one area or a whole building, these details speed things up:
- Where the site is, with the postcode
- The product your specification calls for
- Whether the building will be occupied during the work
- When you need the work done
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 photos and a few notes.
When to call us in South Merstham
UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.
Clients usually get in touch after noticing one or more of the following:
- Water getting in round frames after rain
- Movement joints with sealant missing
- Draught complaints from residents or tenants
- Brittle perimeter mastic across a building
Schools and community buildings such as Merstham Primary School need frame and external mastic kept sound like any building.
Before you book anyone
- Will failed sealant be removed rather than covered?
- Will RAMS and insurance details be available?
- How they’ll work around occupants
- Is the sealant right for the movement and the substrate?
Building owners, agents and FMs in South Merstham
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in South Merstham can sit alongside others in a wider programme across Surrey.
Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Include mastic in your cyclical inspections
- Plan resealing building by building rather than complaint by complaint
- Keep bins and bikes away from communal door frames
- Make it easy for occupiers to report draughts
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
