Construction mastic in Ockham

Site managers want applicators who turn up with the right cards and paperwork. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we are fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We work on brick and block movement joints, sanitary and kitchen joints and cladding and panel joints, and the usual reasons a site gets in touch are new external sealant already peeling away and missed perimeter joints on a new elevation. A single leaking joint is often how a building in Ockham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Ockham, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

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

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Why deal with it now?

Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go. We can run snagging as its own phase before handover. Converted and older buildings near places like Ockham tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

There’s no price list, since every building and every scope is different. Call for a quote.

When it isn’t the sealant

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Frame gaps too wide for sealant, which the installer needs to correct
  • Rework caused by others damaging completed areas
  • Joint design decisions that belong to the architect or engineer

If you are not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Where we work in Ockham

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

Common problems we fix in Ockham

Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond, so preparation matters as much here as on a reseal.

Any of the following is a good reason to get the joints checked over:

  • Sealant knocked or painted over by other trades
  • Missed perimeter joints on a new elevation
  • New external sealant already peeling away
  • Caulk cracking where joints are moving more than expected

School extensions, at buildings such as Ripley Court School, normally run to the summer holidays, mastic included.

Advice

Sites and facades in and around Ockham

Ockham is about 21 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. 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.

With historic properties like Byfleet Manor (to the north of Ockham) in the area, refurbishment work often meets old masonry that needs compatible sealants. For a contractor working at a hospital such as Woking Community Hospital, which lies west of Ockham, perimeter and facade sealing is planned around patients and deliveries.

Ockham is about 5 miles east of Woking, in Surrey. Any commercial site in Ockham is covered. 379 places across Surrey fall within our area, including Ockham. There’s a separate page for London, about 21 miles away.

Questions we are asked in Ockham

Is a hospital such as Woking Community Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Ockham too small for you to travel to?

Not at all. Ockham is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

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, so we will confirm the curing time on the day.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

What do you charge?

It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

Are you CHAS accredited?

We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. We’re also fully insured, with five million pounds of public liability cover.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
