Commercial sealant contractors in Slindon

If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in Slindon, the quickest start is to give us a call on 01277 525 020 or email a schedule or drawings with a list of addresses. Most enquiries involve window and door perimeter joints that have cracked open and a top-up bead over failed sealant, now lifting, across window and door perimeters, movement joints in walls and floors and external facade joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Slindon, preparation and product choice get the time they need.

In an occupied building in Slindon, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.

Business units in the countryside around places like Slindon are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Walls or slabs moving more than any sealant can take
  • Old mastic that tests positive for asbestos
  • Water from a services leak rather than a joint

If you’re not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

What we seal

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

Slindon: questions and answers

Is Slindon too far out for you?

Not at all. Slindon is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is Tokar Industrial Park, near Slindon, within your area?

Yes. Estates, retail parks and business parks around Slindon, Tokar Industrial Park among them, are all within reach. Photos and a short description are enough for a first look.

Can you take on work for an FM or managing agent?

Yes. A large share of our work comes through facilities managers, managing agents and landlords as well as contractors. Tell us how you issue work and we’ll fit in.

Which site documents can you send us?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

How do you keep disruption to occupiers down?

We phase the work so parts of the building stay open. We plan around the site hours and access windows you give us.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Any access equipment needed
  • Location, for remote and island sites
  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Details that help us quote

To price the job accurately, we need to understand the site. Send us:

  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode
  • Photos of the joints, close up and from further back

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or email us.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Check sealant as part of routine building inspections
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Keep a record of which joints were resealed and when

We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records, and tell us if a joint we sealed gives trouble within that time.

Sealant installed at the same time typically fails in sequence. A few splits this year usually mean more next year, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.

Do you need commercial sealant contractors in Slindon?

When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. It’s one of the commonest faults we find on earlier work.

Typical triggers for a call:

  • Leaks that seem to come through a sealant line
  • Wall and floor joints that have lost their seal
  • External beads that have gone brittle and cracked
  • Layers of sealant, all of them failing

In hotels such as Avisford Park Hotel, 1.3 miles to the south-east of Slindon, refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Choosing a commercial sealant contractor

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Slindon are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. Site photos, 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. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.

Getting the site ready

  • Let us know about inductions and permits
  • Share the asbestos register for older buildings
  • Share your working hours and any access restrictions

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
