Coloured sealant in Middleton Stoney

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Coloured sealant in Middleton Stoney

Coloured sealant is a finishing trade, so it usually comes late in a programme. We work around other trades and protect adjacent finishes, and snag any marks before we leave. A 12-month guarantee covers our workmanship. The enquiries we see most involve patch repairs in several different colours and a bead that fights the cladding or frame colour, on cladding panels, shop-fit joinery and counters and natural stone and brick. For commercial sealant work in Middleton Stoney, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Business units in the countryside around places like Middleton Stoney are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • Which sealant the job calls for
  • The size and state of each joint
  • The total length or number of joints
  • Site requirements such as inductions and permits

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • Whether an asbestos survey exists
  • The site address and postcode
  • A wide shot and a close-up of the area
  • Access details, including height

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

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • A colour that never alters with age
  • Paintable products in joints they aren’t suited to
  • Colour variation across natural stone or brick that no single shade can match

If you’re not sure, just give us a call on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

What we seal

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

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

How a job runs

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking a few hours or a phased programme, depending on joint lengths and how many colours are involved. For a building around Middleton Stoney, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We confirm the joint type and the product it needs.
  2. We compare the target colour with the colours available.
  3. The nearest colour is agreed, with a sample bead where needed.
  4. We cut out the existing bead, clean and set the depth.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. Masking comes off and the work is checked with you.

Getting the site ready

  • Send any specification or drawings in advance
  • Tell us which areas need to stay in use
  • Explain the parking and delivery arrangements

Advice

Your questions answered

Is a smaller place like Middleton Stoney outside your area?

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 Middleton Stoney need to close for the work?

Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we will plan around them.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Can staff carry on working while you’re here?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

What the job involves on each surface

Brick and masonry

Brickwork joints typically look best in a colour close to the mortar or brick. The nearest colour in the range is agreed with you.

Powder-coated and anodised frames

Frames finished to a RAL reference are a frequent colour-matching job. The frame colour is checked against what the product is made in.
