Construction mastic across Jealott's Hill

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

Different surfaces, different methods

Snagging before handover

Snags usually come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit, depending on what suits the programme.

Window and door perimeters

Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team.

Construction mastic in Jealott's Hill, done properly

Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. For construction mastic on a scheme in Jealott's Hill, send drawings through our quote form, or phone or email us to talk it through. The enquiries we see most involve early adhesion failures on new external joints and internal caulk splitting as the building dries out, across brick and block movement joints, sanitary and kitchen joints and cladding and panel joints. A single leaking joint is often how a building in Jealott's Hill first comes to us: we look at the rest while we are there and tell you what we find.

Conversions of older rural buildings near smaller places such as Jealott's Hill bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

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.

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Jealott's Hill can sit alongside others in a wider programme across Bracknell Forest.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Your questions answered

Can you work at a site such as Bracknell Enterprise Centre, by Jealott's Hill?

Yes, sites like Bracknell Enterprise Centre are within our area, along with the rest of Jealott's Hill. Send details of the unit and the work through our quote form for a quick quote.

Is a hospital such as Heatherwood Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

What does a mastic package usually include?

Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens, all priced as one package.

Can you work while the building is occupied?

Usually, yes. Phased work can be planned so areas stay in use.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Is the mastic package guaranteed?

It’s backed by our 12-month guarantee. Keeping other trades off finished joints prevents most problems.

What happens if the weather stops external sealing?

External sealing goes ahead only with a dry joint inside the product’s temperature range. Wet or cold joints cause adhesion problems.

Doing it in-house

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

How the quote is worked out

What shapes the price:

  • Any access equipment needed
  • Whether the work must be split into stages
  • Which sealant the job calls for
  • Location, for remote and island sites

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 we need to price the job

Diagnosis starts before we arrive. Let us know:

  • Clear photos of the problem areas
  • Whether the building will be occupied during the work
  • When you need the work done
  • The site address and postcode

For a fixed quote, call the office 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.

Contractors’ notes for Jealott's Hill

Jealott's Hill is about 28 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Jealott's Hill included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.

New units and refits on sites such as Bracknell Enterprise Centre (to the south of Jealott's Hill) need their panel and perimeter joints sealed to the specification. Historic houses such as St Leonard's Hill, 4.5 miles east of Jealott's Hill, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. School extensions, at buildings such as Garth Hill College, usually run to the summer holidays, mastic included.

Jealott's Hill is about 3 miles north of Bracknell, in Bracknell Forest. Anywhere in RG42, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

When something else is needed

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Frame gaps too wide for sealant, which the installer needs to correct
  • Designing joint widths or choosing the specification (that sits with the designer)
  • Deciding which fire-stopping product a penetration needs

If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Where we work in Jealott's Hill

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

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we are 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 Jealott's Hill, 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 we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised right away.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Agree which areas must stay open
  • Explain the parking and delivery arrangements
