Construction mastic for Pirbright sites

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

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Pirbright, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First we take quantities off the drawings and read through the specification.
  2. You receive a fixed quote listing scope, products and phasing.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. We seal each plot or floor as it’s released to us.
  5. Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

What we need from you

  • Arrange parking or a loading space
  • Point out any areas we must not close
  • Send your site hours and access windows

Request a quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Construction mastic for commercial buildings in Pirbright

Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items. Our aim is joints that pass at the first inspection, whatever the size of the scheme. If you’re dealing with perimeter gaps outside the sealant’s range and existing joints on a refurb that need cutting out and resealing, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Pirbright it comes down to the same thing: the right product in a properly prepared joint.

Construction in and around smaller places such as Pirbright 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 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.

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Pirbright can form part of a wider programme.

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

Signs you need construction mastic in Pirbright

A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture and internal caulk in a moving joint is normally the first to crack. Picking a flexible sealant where there’s movement keeps snags down.

If one of these sounds familiar, it’s time for a closer look:

  • External joints sealed in damp or cold conditions that are now failing
  • Perimeter gaps outside the sealant’s range
  • Missed perimeter joints on a new elevation
  • Caulk cracking where joints are moving more than expected

Hospital estates such as Cygnet Hospital, 2 miles to the north-east of Pirbright, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Our contractor checklist

Leave it or put it right?

Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple and a consistent finish. For buildings around smaller places like Pirbright, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why us?

  • Old sealant cut out, never sealed over
  • Colours confirmed for the specified product
  • Sealing commercial buildings since 2005
  • Colours chosen to suit frames, cladding or finishes where possible

Take a look at what affects the cost or our accreditations.

After the work

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

  • Brief the final clean team to avoid blades near sealant
  • Ask installers to correct oversized gaps first
  • Stick to the specified sealant rather than a generic substitute
  • Release areas for mastic once other trades have finished in them

The package carries our 12-month guarantee for workmanship. The guarantee covers how we sealed, not later damage by other trades.

One unsealed frame can let water into finished internal areas. That typically means redoing finishes in a completed area and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.

Pirbright: questions and answers

Could you schedule work at a campus like University of Surrey for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Pirbright too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Do you use the sealant named in the specification?

Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.

Can fire-rated sealing at service penetrations be included?

Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. Fire-stopping design and sign-off sit with the designer and building control.

Do you guarantee new-build sealant work?

Each package is backed by a 12-month guarantee. We are also fully insured for public liability.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

New build and refits around Pirbright

Pirbright is about 28 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. Rainfall across the South East, Pirbright included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.

On a campus such as University of Surrey (3.8 miles south-east of Pirbright), new teaching buildings and residences are typically built and refurbished around the academic year. Projects at colleges like Merrist Wood College (1.8 miles south-east of Pirbright) tend to run to term dates, so the mastic is planned tightly.

Pirbright is about 3 miles south-west of Woking, in Surrey. We send applicators to Pirbright for mastic packages, handled exactly as we handle every other area. 379 places across Surrey fall within our area, Pirbright among them. For work in that direction, see our Reading page (18 miles or so).

Cost factors for mastic packages

Quotes vary with the job. It mainly depends on:

  • Quantities, in metres or numbers
  • Whether the work must be split into stages
  • Induction, permit and paperwork requirements
  • How much existing material needs removing

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

What we need to price the job

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

  • Asbestos survey details if the building is older
  • Drawings or a marked-up plan, if available
  • When you need the work done
  • Where the site is, with the postcode

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
