About our mastic sealing in Church Town

Owners and agents usually inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. We work on shopfronts below residential blocks, external wall and movement joints and balcony and threshold joints, and the usual reasons a site gets in touch are draught complaints from residents or tenants and repeated reactive repairs to the same buildings. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Church Town, preparation and product choice get the time they need.

For owners with a single building near Church Town, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Blocks and managed buildings in Church Town

Church Town has two care or nursing homes no more than 2 miles away. Owners of care premises can bring window and door mastic into a phased programme planned around the home. Church Town is about 17 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.

If you are responsible for a building such as Church of St Nicholas, frame and door mastic needs the same attention as any other property. With historic buildings such as Titsey Place, 3.8 miles to the north-east of Church Town, in the wider area, owners of older properties around Church Town should expect mastic to need a product that suits old masonry.

Church Town is about 3 miles south-east of Caterham, in Surrey. Any commercial site in Church Town is covered, whether it’s a single job or part of a planned programme. We work across 379 places in Surrey, from busy centres to rural villages. For work in that direction, see our London page.

Anyone looking for mastic sealing in RH9 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

If your building is just outside Church Town, we cover Godstone (1 mile west), Tyler's Green (1 mile north-west), Tandridge (1 mile south-east), Bletchingley (2 miles west) and South Godstone (2 miles south).

Common questions from Church Town clients

Is Church Town off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you quote for a block close to Godstone station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you do block-wide mastic programmes?

Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Will residents or tenants be disturbed?

Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.

For managing agents and facilities managers

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

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.

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Church Town may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. A fixed quote follows, split by block or building if that suits you.
  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. Completed joints are inspected and carry a 12-month workmanship guarantee.

Preparing the site

  • Point out any areas we must not close
  • Point out parking and an unloading spot

Related advice

Should maintenance staff do it?

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.

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

Problems stay small when the joints are checked regularly. In particular:

  • Ask residents or tenants to report leaks and draughts early
  • Keep a record of when each building was resealed
  • Group repairs into a planned programme
  • Mention RAMS, insurance or CSCS requirements up front

Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.

The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.

Signs you need mastic sealing in Church Town

UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.

These are often picked up first by site or facilities staff:

  • Complaints coming in block by block
  • Water getting in round frames after rain
  • Damaged joints in communal entrances and corridors
  • Mastic failing across several blocks on an estate

Schools and community buildings such as Godstone Village School need frame and external mastic kept sound like any building.

Questions to ask before you book

  • Who will actually carry out the work
  • Which product they’ll use, and why it suits the joint
  • How the existing material will be dealt with
  • What level of public liability insurance do they hold?

Choosing a commercial sealant contractor

Why act early in Church Town

Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. One visit to deal with every failing joint makes more sense than several trips to a place like Church Town, rather than one at a time. Photos of every joint help us quote for the whole job.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why choose Mastic Doctor in Church Town

  • RAL and finish matching where the product range allows
  • A Constructionline member, so easy to vet
  • CSCS-carded applicators
  • A fixed quote before work starts
