Coloured sealant for businesses in Wantage

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Coloured sealant for commercial buildings in Wantage

Where colour is critical, a sample bead in a discreet spot settles the question. Sealant can look slightly different once it has cured, and again in different light, so seeing it in place helps. Tell us who needs to approve the colour and we’ll plan for it. If you’re dealing with old sealant that has yellowed, darkened or faded and old colour-matched joints lifting at the edges, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Wantage is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller commercial landlords and businesses in a town like Wantage often have a handful of sealant jobs that can go on one visit: say a shopfront perimeter, a tea point, a washroom and some frames. One fixed quote then covers the lot.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Frontages, fit-outs and joints in Wantage

Wantage has five care or nursing homes no more than 2 miles away. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean; colours can be chosen to suit the interior. The 3 miles around Wantage take in at least three named trading estates, business parks or retail parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints.

On a business park such as Elms Farm Business Park (0.6 miles north of Wantage), sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. A hotel such as Blue Boar Hotel, less than half a mile to the south of Wantage, shows how much sealant a hospitality building has on show, from bathroom joints to the bar. If you have premises on more than one site, say at Elms Farm Business Park and Grovelands Shopping Centre, one contractor and one quote can cover both.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes a day for a modest shop fit, and longer for a full building or several floors. For a town like Wantage, we try to group jobs for the same client into one visit. Tell us when the building is open and we’ll plan to suit.

  1. We confirm the joint type and the product it needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  3. The nearest colour is agreed, with a sample bead where needed.
  4. The existing bead comes out, then faces are cleaned and backed.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. Masking comes off and the work is checked with you.

Before we start on site

  • Make sure the joints can be reached
  • Flag any permit to work we will need
  • Tell staff and tenants when we will be in

Getting a fixed quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Overpainting a joint that needs a non-paintable product
  • Stopping sealant from ever changing colour outdoors
  • Finishes that change colour from one area to another

If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

What we seal

  • Hotel bathrooms and public areas
  • Cladding panels
  • Office fit-out finishes
  • Shop-fit joinery and counters
  • Natural stone and brick
  • Powder-coated and anodised frames

Cost factors for colour-matched joints

The price varies from site to site. Expect it to depend on:

  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

What to include in your enquiry

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

  • Any specification or named product
  • The postcode of the building
  • The asbestos register, for older buildings
  • When you need the work done

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or email us if you’d rather talk the job through.

Leave it or put it right?

A brand roll-out or multi-site fit-out benefits from a consistent sealant colour. Setting one product and colour for every site avoids variation. In a town like Wantage, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why clients in Wantage choose us

  • Over 20 years of commercial sealing
  • CHAS accredited contractor
  • Constructionline member
  • Joints cleaned back to sound surfaces

Wantage: questions and answers

Will you take on work at estates like Elms Farm Business Park, close to Wantage?

Yes. Our area takes in Wantage and its surroundings, with estates and business parks such as Elms Farm Business Park included. Photos and a short description are enough for a first look.

What paperwork can you provide for a job in Wantage?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

How do you choose the sealant?

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.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
