Construction mastic for commercial buildings in Crookham

On a new build, the mastic package is one of the last trades through each area, which puts it right on the critical path. We work as a mastic subcontractor to main contractors and developers, sealing plot by plot or floor by floor as areas are released. If you’re dealing with missed perimeter joints on a new elevation and failed sealant in an existing building being refurbished, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Crookham it comes down to the same thing: the right product in a properly prepared joint.

Construction in and around smaller places such as Crookham 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.

Every job we finish is backed by a 12-month workmanship guarantee, in Crookham as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the job changes by surface

Snagging before handover

Snags usually come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately, depending on what suits the programme.

Fire-rated sealant where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control; we work to the specification and the manufacturer’s installation guidance.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Record the products used in the O&M file
  • Check frame gaps are within the sealant’s range before sealing
  • Put any product change through the designer first
  • Allow flexibility for external sealing in damp or cold weather

A new structure shifts as it loses construction moisture. The right product in each joint copes with that while rigid fillers and caulk can crack where movement is larger. We can advise if a joint needs a different product.

One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. A check of every frame before decorators start is worth the time.

How a job runs

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Crookham may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Problems we find, such as oversized gaps, are raised right away.
  6. Final snagging is completed and the 12-month guarantee applies.

Preparing the site

  • Point out any areas we must not close
  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements

What we are called out for in Crookham

A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.

Common reasons buildings call us in:

  • Frame perimeters left unsealed or poorly sealed
  • Early adhesion failures on new external joints
  • Sanitary sealant damaged by following trades
  • A mastic package split between trades with no clear owner

Projects at schools like Brimpton C.E. Primary School work to term dates, so mastic is programmed tightly.

Comparing quotes

  • What level of public liability insurance do they hold?
  • How long is the guarantee, and what does it include?
  • Their pre-qualification and accreditations
  • Which product they’ll use, and why it suits the joint

Questions to ask before you appoint anyone

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Frame gaps too wide for sealant, which the installer needs to correct
  • Approving fire stopping as compliant
  • Faulty frames rather than failed sealant

Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly.

Surfaces we seal

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

Construction mastic in Crookham: the local picture

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. Crookham is about 49 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

With historic properties like Shaw House, 5 miles to the north-west of Crookham, in the area, refurbishment work often meets old masonry that needs compatible sealants. Units on estates such as Colthrop Industrial Estate, 1.4 miles to the north of Crookham, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Crookham is about 3 miles south-east of Thatcham, in West Berkshire. Anywhere in RG7, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Crookham is one of 140 places we cover in West Berkshire. Our Reading page has more on work in that area (12 miles or so).

Work on mastic packages is covered throughout RG7 and RG19, whatever the building. If your site is on Crookham Common Road and Hyde End Lane or close by, we can quote for mastic packages. If your building is just outside Crookham, we cover Hyde End (1 mile south-east), Goose Hill (1 mile south-west), Mill Green (1 mile south-west), Ashford Hill (2 miles south-east) and Plastow Green (2 miles south-west). Bigger towns within reach include Newbury (5 miles west), Thatcham (3 miles north-west), Burghfield Common (7 miles east), Speenhamland (5 miles north-west), Hungerford (13 miles west) and Fords Farm (9 miles north-east).

Local landmarks in Crookham

We work on buildings around Kennet School and The Travellers Friend pub and the streets around them. The nearest railway station is Thatcham station, about 1.6 miles north-west of the centre. Other landmarks nearby include Old Chapel Textile Centre (2.7 miles west) and West Berkshire Community Hospital (3.8 miles north-west). Open spaces near Crookham include Thatcham Reed Beds.

Your questions answered

Can you work at a site such as Colthrop Industrial Estate, by Crookham?

Yes. We cover Crookham and the area around it, including industrial estates, business parks and retail parks such as Colthrop Industrial Estate. Photos and a short description are enough for a first look.

Can you work on a hospital site such as West Berkshire Community Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How do we ask for a quote?

There are 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 your applicators hold CSCS cards?

We are CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. We confirm any paperwork you need with the quote.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

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

Where it’s specified, yes. We will flag if the detail needs a different product.

Can the sealant be colour-matched?

It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
