Mastic sealing for Godstone sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle mastic sealing in Godstone

For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. The enquiries we see most involve the same joint failures repeated across a portfolio and window mastic that has split and shrunk, across window and door perimeters on blocks, communal entrances and stairwells and external wall and movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Godstone it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Owners and agents with buildings around smaller places such as Godstone tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What happens if it’s left?

Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Around Godstone, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • Distance, for remote addresses
  • Phasing around occupants
  • The site’s rules and procedures
  • Any access equipment needed

Pricing mastic joints depends on quantities, condition and access. Ask us for a fixed quote.

Details that help us quote

We can often quote from photos and a few details. It helps to include:

  • The postcode of the building
  • The asbestos register, for older buildings
  • Any dates the work must fit around
  • Rough lengths or quantities, or drawings if you have them

To get a fixed quote, phone 01277 525 020 or use the quote form. You can also send details through our quote form.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Masonry that has broken away beside the joint
  • Broken glass or failed sealed units
  • Failed window or door frames, which need a window contractor

If you’re not sure, just give us a call on 01277 525 020 or email the details over and we’ll give you a straight answer.

What we seal

  • External wall and movement joints
  • Communal kitchens and washrooms
  • Window and door perimeters on blocks
  • Communal entrances and stairwells
  • Shopfronts below residential blocks
  • Balcony and threshold joints

Planned mastic for Godstone portfolios

Godstone is about 17 miles from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. Rainfall across the South East, Godstone included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

Site managers at schools like Godstone Village School can fit frame mastic into the summer works. Historic properties like Titsey Place, 4.1 miles north-east of Godstone, show the age of some local stock, where frame mastic must suit soft brick or stone.

Godstone is about 3 miles south of Caterham, in Surrey. Across the RH9 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 379 places in Surrey, from busy centres to rural villages. There’s a separate page for London, about 17 miles away.

Commercial sites across RH9 are covered. Streets here include High Street, Court Road and Godstone Green Road, and sites on any of them can send details for a fixed quote. Just outside Godstone, we also work in Tyler's Green (1 mile north), Church Town (1 mile east), Bletchingley (2 miles west), Tandridge (2 miles south-east) and South Godstone (2 miles south). A short drive away, we cover Epsom (11 miles north-west), Horley (7 miles south-west), Redhill (4 miles west), Ewell (11 miles north-west), Reigate (6 miles west) and Caterham (3 miles north).

Around Godstone

Around Godstone, our work takes us to commercial buildings near The Hare And Hounds Public House and Bay Pond. Godstone’s nearest station is Godstone station, about 2.2 miles south. Other landmarks nearby include Caterham Dene Hospital (2.5 miles north) and Bletchingley Castle (1.9 miles west). For a walk, there’s Mercers Lake and Bay Pond.

When to call us in Godstone

UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.

Things that usually lead to an enquiry:

  • No planned programme for sealant
  • Water getting in round frames after rain
  • Estate-wide sealant that is simply worn out
  • Occupiers reporting cold air round windows

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.

Questions to ask before you book

  • How the existing material will be dealt with
  • Proof of insurance
  • How they’ll work around occupants
  • Whether their applicators hold CSCS cards

Our contractor checklist

Aftercare for building managers

To get the most from the new sealant:

  • Look at the sunniest and most exposed elevations first
  • Encourage occupiers to report problems at frames
  • Share the asbestos register when you send details
  • Group repairs into a planned programme

If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.

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

FAQs: Godstone

Can you quote for a block close to Godstone station?

Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.

Is Godstone off your patch?

No. Places such as Godstone are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Is asbestos a concern with old mastic?

We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.

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.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you plan resealing across several buildings?

Block-wide and estate programmes are common. The quote can be split however suits your budgeting.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. For work around Godstone, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. A fixed quote covers the joints, products and order of work.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

What we need from you

  • Tell us your opening times and when work is allowed
  • Tell us which areas need to stay in use
  • Let building users know which areas are affected
