Construction mastic for Westfield sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Construction mastic in Westfield, done properly

Getting a subcontractor through site induction should be simple. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, with public liability insurance in place. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. The enquiries we see most involve snag items on joints that need redoing before handover and sealant knocked or painted over by other trades, on floor and skirting junctions, cladding and panel joints and sanitary and kitchen joints. Most enquiries from Westfield start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

For a contractor on a smaller site near Westfield, one mastic visit at the right stage saves return trips. Let us know the key stages and we will time the work so nothing waits on us.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

When it isn’t the sealant

Being straight saves everyone time. Fresh joints won’t solve:

  • Frames fitted out of tolerance
  • Faulty frames rather than failed sealant
  • Damage to finishes by other trades after we’ve sealed

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think.

What we seal

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

Cost factors for mastic packages

Your fixed quote is built from the real scope. It allows for:

  • Joint width, depth and condition
  • The product specified
  • Distance, for remote addresses
  • Induction, permit and paperwork requirements

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What to include in your enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • When you need the work done
  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back
  • Access details, including height

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to call 01277 525 020 or send details through our quote form.

Commercial clients in Westfield

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

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.

What the job involves on each surface

Fire-rated sealant where specified

Not every penetration suits a sealant. Other products are used for some services and gaps so we will flag where the detail needs something different. Tell us what records you need and we’ll confirm with the quote.

External facade and movement joints

Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it and work only when conditions suit.

Westfield: questions and answers

Can you take on a job at a hospital such as Woking Community Hospital?

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.

Will you take on work at estates like Martlands Industrial Estate, close to Westfield?

Yes. We cover Westfield and the area around it, including industrial estates, business parks and retail parks such as Martlands Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Can you clear a mastic snag list before handover?

Yes. We can work through a mastic snag list area by area before handover, cutting out damaged or poor joints and resealing them.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can the building stay open while you work?

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

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Why act early in Westfield

On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal, which is a much smaller cost. We will say so if a frame itself is the problem. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

A quote for mastic packages depends on quantities, condition and access. Call for a quote.

Facades, frames and programmes in Westfield

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 the external programme keeps a little slack. The area within 2 miles of Westfield holds a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

On a healthcare site such as Woking Community Hospital, 1 mile to the north of Westfield, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Projects at colleges like Woking College, 0.7 miles north-east of Westfield, tend to run to term dates, so the mastic is planned tightly. Hotels like DoubleTree by Hilton Hotel Woking, 1.5 miles north of Westfield, rarely close for long, so refurbishment mastic is phased floor by floor.

Westfield is about 1 mile south-east of Woking, in Surrey. We send applicators to Westfield for mastic packages, handled exactly as we handle every other area. Westfield is one of 379 places in Surrey on our list for mastic packages. We also cover Reading, around 21 miles from Westfield.

Postcode districts covered here: GU22. We cover commercial and managed buildings on Ash Road, Moor Lane and Loop Road. Main routes into Westfield include the A247, useful when we plan access and materials. If your building is just outside Westfield, we cover Old Woking (1 mile east), Woking (1 mile north-west), Goldsworth Park (1 mile north-west), St John's (2 miles north-west) and Horsell (2 miles north). Bigger towns within reach include Guildford (4 miles south), Camberley (8 miles west), Epsom (13 miles east), Farnham (12 miles south-west), Ewell (14 miles east) and Egham (9 miles north).

Local landmarks in Westfield

Locally, jobs take us to sites close to Hoe Valley School, Hoe Valley School and Hoe Valley Linear Park. The nearest railway station is Woking station, about 1.2 miles north of the centre. A little further out are Woking Community Hospital (1 mile north) and Guildford Castle (4.7 miles south). The countryside around Westfield includes Pewley Hill and Boldermere Lake.

From enquiry to sign-off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes whatever the programme allows, since the work follows the trades as areas are released, and our waste is bagged and taken away as we go. Several jobs near Westfield can be grouped on one trip. Mention the building’s opening times and we’ll work within them.

  1. Drawings, the sealant specification and your programme come to us for pricing.
  2. A fixed quote sets out the scope, the products and the sequence.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. Areas are sealed plot by plot or floor by floor as the trades hand them over.
  5. Each joint is prepared, backed to depth and sealed in the product the specification names.
  6. Snags are cleared before handover and completed areas carry our 12-month guarantee.

Before we start on site

  • Share your working hours and any access restrictions
  • Arrange parking or a loading space
  • Point out any areas we must not close
