Mastic sealing across Wrotham Heath

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Mastic sealing in Wrotham Heath, done properly

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. If you have complaints coming in block by block and damaged joints in communal entrances and corridors, we can help, whatever the surface. For commercial sealant work in Wrotham Heath, you deal with one contact from quote to sign-off, whether it’s one building or several.

Owners and agents with buildings around smaller places such as Wrotham Heath tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep a record of when each building was resealed
  • Share your contractor requirements early
  • Reduce knocks to communal area joints
  • Have the asbestos survey to hand for older buildings

Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.

Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.

Questions we are asked in Wrotham Heath

Does your area include sites such as Invicta Business Park, near Wrotham Heath?

Yes. Estates, retail parks and business parks around Wrotham Heath, Invicta Business Park among them, are all within reach. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Do you work for managing agents with blocks near Borough Green & Wrotham station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.

Is asbestos a concern with old mastic?

Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.

Do you work in Wrotham Heath?

Yes. We take on work across Wrotham Heath, with one number for every area we cover.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you work with property factors and landlords?

Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day.

What we’re called out for in Wrotham Heath

Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Cleaning products add to the wear.

Clients typically get in touch after noticing one or more of the following:

  • Repeated reactive repairs to the same buildings
  • Leaks at window and door perimeters
  • Mastic failing across several blocks on an estate
  • Brittle perimeter mastic across a building

Older community buildings, Church of St Margaret among them, often have frames of mixed ages whose mastic varies.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • Will RAMS and insurance details be available?
  • Proof of insurance
  • Are they CHAS accredited or on Constructionline?

Our contractor checklist

Frames, entrances and external joints in Wrotham Heath

Wrotham Heath sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Wrotham Heath is about 24 miles from central London. Within reach of London, blocks run by agents and associations are common around stations.

With historic buildings such as Old Soar Manor (to the south-west of Wrotham Heath) in the wider area, owners of older properties around Wrotham Heath should expect mastic to need a product that suits old masonry. Landlords with units on estates such as Invicta Business Park, 1.1 miles to the north-west of Wrotham Heath, can bring frame, door and external mastic across several units into one programme.

Site staff or a sealant specialist?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What affects the price in Wrotham Heath

Your fixed quote is built from the real scope. It takes account of:

  • How much there is to seal
  • Site requirements such as inductions and permits
  • Phasing around occupants
  • How accessible the joints are

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Before you send an enquiry

There’s no need for a formal survey. These details are enough to start:

  • When you need the work done
  • The type of building and who uses it
  • Approximate linear metres or a joint schedule
  • The site address and postcode

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or send photos by email.

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes anything from a day to a few weeks, depending on the number of buildings and joints. If others near Wrotham Heath need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Flag any permit to work we’ll need
  • Have the specification and drawings to hand
