Mastic sealing in Merle Common, done properly

Across Merle Common and the rest of Surrey, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. Most enquiries involve communal area joints that look neglected and movement joints with sealant missing, on balcony and threshold joints, window and door perimeters on blocks and external wall and movement joints. Facilities teams, main contractors and managing agents in Merle Common tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Merle Common, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Block-wide mastic in Merle Common

Merle Common sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building usually need attention first. At about 19 miles from central London, Merle Common is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.

If you look after a block within reach of Hurst Green station, which lies north of Merle Common, frame and balcony mastic can be renewed on one programme. Historic properties like Chartwell (3.3 miles north-east of Merle Common) show the age of some local stock, where frame mastic must suit soft brick or stone. If your remit includes a building such as Holland Junior School, frame and door mastic can be programmed for the holidays.

Merle Common is about 6 miles south-east of Caterham, in Surrey. Commercial clients in Merle Common use us for work on mastic joints. Merle Common is one of 379 places in Surrey on our list for mastic joints. Sites around London have their own page, about 19 miles away.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Merle Common may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Before we start on site

  • Let us know about inductions and permits
  • Move anything stored against the joints
  • Send any specification or drawings in advance

Ask for a quote

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Quoting for work in Merle Common

The price varies from site to site. It mainly depends on:

  • The size and state of each joint
  • Site requirements such as inductions and permits
  • How much there is to seal
  • Removal of failed or old sealant

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.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them
  • Asbestos survey details if the building is older
  • Any specification or named product

For a fixed quote, give us a call on 01277 525 020 or use the quote form with the site address and an outline of the work. You can also send details through our quote form.

Why it’s worth doing now in Merle Common

Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work and less choice about when. For buildings around smaller places like Merle Common, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

There’s no price list, since every building and every scope is different. Call for a quote.

Merle Common: questions and answers

Is a smaller place like Merle Common outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you quote for mastic across several buildings in and around Merle Common?

Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we will give a fixed quote.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

How long does a job like this take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Different surfaces, different methods

Estate-wide resealing programmes

A programme can start with the worst buildings and work down. You get one fixed quote per building or for the whole estate.

Tenement and older buildings

Older mastic can contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.

When to bring in a specialist

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
