Commercial mastic work in Penton Hook

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. We work on window and door perimeters, external facade joints and movement joints in walls and floors, and the failures we’re asked to look at most are external beads that have gone brittle and cracked and damp patches where an external joint has failed. Whether you call it commercial sealant work, mastic application or joint sealing, in Penton Hook it comes down to the same thing: the right product in a properly prepared joint.

In Penton Hook, as anywhere, the first joints to go are normally the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.

Commercial sealant work around smaller places like Penton Hook tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

A 12-month guarantee applies to all our work in Surrey. If an installation problem shows up, ring 01277 525 020 or use the quote form and we will arrange a return visit.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Log reseals in the O&M or maintenance records
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Act on the first lifting edges rather than waiting
  • Add sealant to the planned maintenance inspection list

Give fresh sealant time to cure before it’s cleaned, wetted or walked past. That time depends on the product, the temperature and the joint depth, and we confirm it when each area is handed back. Leaving the area closed until then keeps the bead neat.

Occupiers often notice failing sealant before the facilities team does. Replacing it on a planned cycle keeps complaints down.

Leave it or put it right?

Patching the worst lengths can be the right call on a tight budget. If the rest of the bead is the same age and product, though, it’s normally close behind. Where it helps, we quote a patch and a full reseal side by side. One visit to deal with every failing joint makes more sense than several trips to a place like Penton Hook, rather than one at a time. Photos of every joint help us quote for the whole job.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why appoint us

  • Public liability insurance in place

Commercial sealant contractors around Penton Hook: points for this area

Less than 3 miles from Penton Hook there are at least three named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies. The South East is one of the drier parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.

For premises near Chertsey station, 1.5 miles to the south of Penton Hook, footfall is part of the plan: work is phased so shops and offices keep trading. In hotels such as The Olde Swan Hotel, 1.1 miles south of Penton Hook, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. If you have premises on more than one site, say at Thorpe Industrial Estate and Egham Business Park, one contractor and one quote can cover both.

FAQs: Penton Hook

Is Penton Hook off your patch?

Not at all: smaller places are covered as well as towns. 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.

Will our hotel in Penton Hook need to close for the work?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

How many days will you need on site?

It depends on the scope, but the work normally takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For bigger or phased jobs, we will set out a timescale with the quote.

Will the building have to shut during the work?

That comes down to planning: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we’ll plan the job around it.

What guarantee do you give on resealing?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

Which site documents can you send us?

Send your site requirements with the enquiry. For older buildings we will ask for the asbestos register, plus your site induction rules.

Can one contractor look after sealant on all our buildings?

Yes. Send a list of addresses and what’s needed at each, and fixed prices follow, with a suggested sequence.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Structural cracks or movement the joints weren’t designed for
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Suspect materials that need testing and specialist removal

If in doubt, ring 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

  • Window and door perimeters
  • Movement joints in walls and floors
  • Kitchen worktops and splashbacks
  • Floor and threshold joints
  • External facade joints
  • Washrooms and tea points

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Distance, for remote addresses
  • Backing rod, priming and other preparation
  • Whether the work must be split into stages
  • Induction, permit and paperwork requirements

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • What the building is and how it’s used
  • Any specification or named product
  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, ring 01277 525 020 or send details through our quote form.

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Penton Hook need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Preparing the site

  • Make sure the joints can be reached
  • Let building users know which areas are affected
  • For older buildings, check the asbestos register before work
