Honest limits

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Suspect materials that need testing and specialist removal
  • Cracking that needs a structural engineer to look at it
  • Faulty windows rather than failed perimeter sealant

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly.

Where we work in Banbury

  • Washrooms and tea points

About our commercial sealant contractors in Banbury

Sealant joints are easy to overlook until one lets water in, and on a working site that typically surfaces as a leak, a stain or a complaint from occupiers. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. If you have black mould through washroom sealant that won’t clean off and weathered facade sealant that no longer flexes, we can put it right. One point of contact handles commercial sealant work in Banbury from the first photos to the final walk-round, whether it’s one building or several.

Quotes for commercial sealant in Banbury can come from photographs and a joint schedule, or from a walk-round, and the scope is set out in writing.

For a business or landlord in Banbury with one or two premises, it makes sense to bundle sealant jobs together: say a shopfront perimeter, a tea point, a washroom and some frames. A single fixed quote covers everything on the list.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What happens if it’s left?

Spot repairs have their place. If the rest of the bead is the same age and product, though, it’s usually close behind, so access and set-up end up being paid for twice. Where it helps, we quote a patch and a full reseal side by side. For businesses and landlords in Banbury, a tidy, sound joint also matters for appearance. Renewing it keeps the building looking cared for.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why appoint us

  • A range of standard colours, depending on the product
  • Colour options checked against the specified product
  • Failed material removed, not covered up
  • CHAS accredited

General trades versus a specialist

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.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Our process

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Town-centre premises in Banbury may have limited parking, so tell us what’s nearby. On estates and business parks it’s normally simpler.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Getting the site ready

  • Flag any permit to work we’ll need
  • Confirm the product named in the specification
  • Arrange parking or a loading space

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Surface by surface

Shop fronts and retail fit-outs

Most shops can’t close for a reseal. We plan around the access windows the store gives us, phasing areas so the shop floor stays usable.

Movement joints in walls and floors

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

Common problems we fix in Banbury

Washrooms and kitchens wear sealant out in their own way. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant. The fix is a new bead of anti-mould sanitary silicone.

What tends to prompt an enquiry:

  • Frame sealant that has cracked, shrunk or pulled away
  • Sanitary sealant that has gone black and patchy
  • Shrunken sealant along kitchen worktops and splashbacks
  • External beads that have gone brittle and cracked

In hotels such as Cromwell Lodge Hotel (under half a mile east of Banbury), refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

How to choose a sealant contractor

Banbury: questions and answers

Will you take on work at estates like Swan Industrial Estate, close to Banbury?

Yes, sites like Swan Industrial Estate are within our area, along with the rest of Banbury. Send details of the unit and the work through our quote form for a quick quote.

Do you offer colour-matched sealant for buildings in Banbury?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do you check for asbestos before removing sealant?

It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

How long does a job like this take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Can you supply RAMS and insurance details?

We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

Commercial sealant contractors in Banbury: the local picture

Banbury has eight care or nursing homes no more than 2 miles away. Care homes need tidy, cleanable joints in kitchens, corridors and communal rooms, often in colours that suit the décor. At least three named trading, business or retail sites lie within about 3 miles of Banbury. Each new occupier on a park like these tends to refit, from reception to staff kitchen; brand colours often come into it.

Units at places like Castle Quay Shopping Centre (to the east of Banbury) are refitted as brands change, and the joints have to suit each new scheme. A business with units at Swan Industrial Estate and Southam Road Retail Park needn’t use two contractors for its sealant.
