Construction mastic for commercial buildings in Fair Oak

On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. After that, the joints are prepared and sealed to the specification. We work on brick and block movement joints, window and door perimeters and floor and skirting junctions, and the usual reasons a site gets in touch are different trades sealing to different standards and sanitary sealant damaged by following trades. Facilities teams, main contractors and managing agents in Fair Oak tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Conversions of older rural buildings near smaller places such as Fair Oak 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 usually what’s needed.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep scrapers and abrasive pads off new beads
  • Keep product details for future maintenance
  • Use the product the specification names
  • Allow flexibility for external sealing in damp or cold weather

Record which products went where in the handover file. That helps the building owner maintain the joints later, and tells you what to reseal with. Tell us what records you need and we’ll confirm with the quote.

Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out.

Building owners, agents and FMs in Fair Oak

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

On site: what to expect

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Smaller jobs around Fair Oak can be grouped with others nearby. You will have a fixed quote before work starts.

  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. We seal plot by plot or floor by floor in line with the programme.
  5. Any frame gaps or issues outside our scope are flagged to the site team.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

What we need from you

  • Have the specification and drawings to hand
  • Warn occupants and staff about the work
  • Agree which areas must stay open

Your questions answered

Is Fair Oak too far out for you?

Not at all. Fair Oak is within our area. 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.

Is hospital work, at somewhere like West Berkshire Community Hospital, something you do?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Do you install fire-rated sealant as part of a package?

It can be part of the package where specified. Record requirements are confirmed at quote stage.

Can staff carry on working while you’re here?

In the majority of cases, yes. We phase the work so most of the building stays in use.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Building and refurbishing in Fair Oak

Fair Oak sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Fair Oak lies roughly 49 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.

When a school such as Ashford Hill Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. New units and refits on sites such as Scion Business Park (to the north-east of Fair Oak) need their panel and perimeter joints sealed to the specification.

Fair Oak is about 3 miles west of Tadley, in Hampshire. Any commercial site in Fair Oak is covered, for single jobs and planned programmes alike. We work across 723 places in Hampshire. Sites around Reading have their own page, roughly 12 miles from Fair Oak.

Business premises anywhere in RG19 are within our area. If your building is just outside Fair Oak, we cover Ashford Hill (1 mile north), Plastow Green (1 mile west), Wolverton (1 mile south), Goose Hill (1 mile north-west) and Hyde End (2 miles north). Nearby towns on our patch include Basingstoke (7 miles south-east), Andover (15 miles south-west), Tadley (3 miles east), Hook (12 miles east), Popley (7 miles south-east) and Kempshott (8 miles south-east).

What’s near Fair Oak

Around Fair Oak, our work takes us to commercial buildings near The Hurst School and the streets around them. The nearest railway station is Thatcham station, about 3.6 miles north-west.

Different surfaces, different methods

External facade and movement joints

Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.

Internal decorators’ caulk

Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted.

When to call us in Fair Oak

Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.

Typical triggers for a call:

  • Snag items on joints that need redoing before handover
  • A mastic package split between trades with no clear owner
  • New external sealant already peeling away
  • Caulk cracking where joints are moving more than expected

New wings at hospitals like West Berkshire Community Hospital (to the north-west of Fair Oak) bring long runs of window and panel joints to seal.
