Commercial sealant contractors in Woking

Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us, handled with the same process each time: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Woking, speak to us on 01277 525 020 or email us with the site addresses. If you are dealing with external beads that have gone brittle and cracked and window and door perimeter joints that have cracked open, we can help. Facilities teams, main contractors and managing agents in Woking tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Multi-site clients with buildings in and around Woking can put several sites on one programme, so standards and paperwork match across every site.

A large place such as Woking tends to have every kind of commercial building: business parks, retail centres, hotels, surgeries and offices above the high street. That variety is why a single contractor covering several premises can help, with colours kept consistent site to site where a brand needs it.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Our process

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes part of a day on a small job and longer where several buildings or phases are involved, and we clear our waste as we work. In a large town like Woking, work on busy buildings is planned area by area, keeping disruption low. Photos and drawings let us propose a sequence with the quote.

  1. First, details come to us: photographs, drawings or a schedule of the areas, and a site visit is booked where it helps.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Preparing the site

  • Tell us which areas need to stay in use
  • Explain the parking and delivery arrangements
  • Share your working hours and any access restrictions

Related advice

Woking: questions and answers

Can you work at a site such as Goldsworth Park Trading Estate, by Woking?

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

Can you supply sealant in our brand colour for a site in Woking?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

Is failed sealant stripped out, or sealed over?

Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.

Do you check for asbestos before removing sealant?

Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested.

How many days will you need on site?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Do you work for facilities managers and managing agents?

Yes. You can send details through our quote form, and we’ll confirm any paperwork you need with the quote.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Travel to remote or island sites
  • The site’s rules and procedures
  • Whether the work must be split into stages
  • Access and working height

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What we need to price the job

It doesn’t need to be a full survey. These details are enough to start:

  • Where the site is, with the postcode
  • Any specification or named product
  • Drawings or a marked-up plan, if available
  • Photos of the joints, close up and from further back

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Cracking that needs a structural engineer to look at it
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Roof leaks that only look like a joint problem

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.

What we seal

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

Surface by surface

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. We’ll recommend the right filler or sealant for the traffic and movement.

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, phasing the rooms so not every toilet is closed at once.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Note dates and locations of sealant work for future planning
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Check sealant as part of routine building inspections
  • Act on the first lifting edges rather than waiting

Keep an eye out for other trades after we have gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just phone 01277 525 020 or email the details over for a quote.

Tenants and staff spot black or split sealant quickly. Planned replacement saves fielding the same complaint again and again.

What Woking’s businesses ask us to seal

Rainfall across the South East, Woking included, is lower than in many parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. At least three named trading, business or retail sites lie within about 3 miles of Woking. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints; brand colours often come into it.

If you run a unit on an estate such as Goldsworth Park Trading Estate (0.8 miles north-west of Woking), the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Refits at hotels like DoubleTree by Hilton Hotel Woking (to the north-east of Woking) bring joints at vanity tops, bars and reception desks that guests see every day.

Do you need commercial sealant contractors in Woking?

Resealing over the top is a false economy we come across often. New silicone has nothing to key into, so the top layer lifts, holds water and hides what’s going on. Getting back to a clean joint then means removing every layer.

What tends to prompt an enquiry:

  • Messy, uneven beads from earlier work that let the building down
  • Weathered facade sealant that no longer flexes
  • Wall and floor joints that have lost their seal
  • Window and door perimeter joints that have cracked open

Sites a few miles apart, such as Goldsworth Park Trading Estate and Lion Retail Park, can share one programme and one point of contact.
