Building and refurbishing in Mereworth

Mereworth lies roughly 26 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. Mereworth is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.

When a school such as Mereworth Community Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. For contractors refurbishing units at places like The Alders Industrial Estate, 0.5 miles south-west of Mereworth, the mastic covers cladding panels, roller-door and window perimeters.

Mereworth is about 6 miles north-east of Tonbridge, in Kent. Mereworth sits inside our coverage and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

Construction mastic in Mereworth

Mastic is often where a new building first shows its quality to the client. Untidy or missed joints are among the commonest snag items, and every return visit costs time. We seal so the snag list stays short, area by area through the programme. Most enquiries involve mastic snags holding up handover and cracks opening in caulked internal joints, on sanitary and kitchen joints, internal decorators’ caulk and floor and skirting junctions. A single leaking joint is often how a building in Mereworth first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Mereworth, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. For a building around Mereworth, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Any frame gaps or issues outside our scope are flagged to the site team.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

Getting the site ready

  • Arrange parking or a loading space
  • For older buildings, check the asbestos register before work
  • Tell us which areas need to stay in use

Advice

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Approving fire stopping as compliant
  • Frame gaps too wide for sealant, which the installer needs to correct

If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think.

Where we work in Mereworth

  • Window and door perimeters
  • Floor and skirting junctions
  • Cladding and panel joints
  • Sanitary and kitchen joints
  • Internal decorators’ caulk
  • Brick and block movement joints

Quoting for work in Mereworth

There’s no standard rate for sealant work, because every site is different. What we look at:

  • The total length or number of joints
  • Whether the work must be split into stages
  • Distance, for remote addresses
  • How accessible the joints are

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available
  • Clear photos of the problem areas

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. If you have questions first, give us a call on 01277 525 020 or email drawings and photos.

Common questions from Mereworth clients

Is a hospital such as Maidstone Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Mereworth too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you take on mastic snagging only?

Yes. Damaged, missed or untidy joints are stripped and done again properly, working to your handover date.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

How much does the work cost?

We don’t publish prices, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

For managing agents and facilities managers

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Mereworth. One quote can cover more than one site, which keeps the paperwork simple.

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Common problems we fix in Mereworth

A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.

Any of the following is a good reason to get the joints checked over:

  • Bath and shower joints scraped during the final clean
  • Cracks opening in caulked internal joints
  • A mastic package split between trades with no clear owner
  • Failed sealant in an existing building being refurbished

Historic houses such as Old Soar Manor, 2.5 miles to the west of Mereworth, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Before you book anyone

  • How the joint faces will be prepared and primed
  • What site paperwork they can supply
  • Are they CHAS accredited or on Constructionline?
  • Their plan for phasing and protecting the area

Our contractor checklist

What the job involves on each surface

External facade and movement joints

External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it.

Fire-rated sealant where specified

Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps. Tell us what records you need and we’ll confirm with the quote.
