Construction mastic in Keeper's Corner

Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. Sealing too early only means coming back once others have damaged it. We work on brick and block movement joints, cladding and panel joints and internal decorators’ caulk, and what we’re called in for most is snag items on joints that need redoing before handover and perimeter gaps outside the sealant’s range. Whoever orders the work in Keeper's Corner, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Construction in and around smaller places such as Keeper's Corner is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Construction mastic in Keeper's Corner: the local picture

Keeper's Corner lies roughly 24 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. There are a number of hotels within about 2 miles of Keeper's Corner. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

When units on a site such as Redeham Hall Industrial Estate (less than half a mile north of Keeper's Corner) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Hotels like Copthorne Hotel Effingham Park, 1.1 miles south-east of Keeper's Corner, rarely close for long, so refurbishment mastic is phased floor by floor. For contractors at a school such as Copthorne CofE Junior School, sealing has to be finished before term starts.

Keeper's Corner is about 3 miles south-east of Horley, in Surrey. Commercial clients in Keeper's Corner use us for work on mastic packages, as part of our coverage of Surrey.

Leave it or put it right?

Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility. Converted and older buildings near places like Keeper's Corner tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Why us?

  • 12-month guarantee on workmanship
  • Coloured sealants to suit the setting, where available
  • Colours chosen to suit frames, cladding or finishes where possible
  • Health and safety: CHAS accredited

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Joint design decisions that belong to the architect or engineer
  • Rework caused by others damaging completed areas
  • Frames fitted out of tolerance

If in doubt, call 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

What we seal

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

What sets the cost

These are the things that shape the price:

  • Travel to remote or island sites
  • Phasing around occupants
  • Removal of failed or old sealant
  • Site requirements such as inductions and permits

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • Any dates the work must fit around
  • Approximate linear metres or a joint schedule
  • Access details, including height
  • The product your specification calls for

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email us.

Keeper's Corner: questions and answers

Is a hospital such as Langley Green Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is a smaller place like Keeper's Corner outside your area?

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

How long does a typical visit take?

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

Will you stick to the specified products?

We use the product the specification names. Any suggested alternative is put to you before anything changes.

Can the building stay open while you work?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

For managing agents and facilities managers

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Keeper's Corner can form part of a wider programme across Surrey.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
