What we’re called out for in Stone

A change of finish can leave existing sealant mismatched. Refurbishments and rebrands often bring a new colour scheme.

Common reasons buildings call us in:

  • Hotel refurbishments with a set colour scheme
  • A run of joints in mismatched shades
  • A bead that fights the cladding or frame colour
  • Marked sealant in hotel bathrooms

Retail sites such as Bluewater Shopping Centre, under half a mile south of Stone, are typical of where shop-fit joints, frontages and staff areas need neat, colour-matched sealant.

What to look for in a quote

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will failed sealant be removed rather than covered?
  • What level of public liability insurance do they hold?
  • Will RAMS and insurance details be available?

About our coloured sealant in Stone

Stone, brick and cladding each bring their own colour challenge: a stone or brick facade shifts in tone from one area to the next. The aim is a sealant colour that sits comfortably against the whole surface, agreed on site where needed. We work on office fit-out finishes, natural stone and brick and cladding panels, and what we are called in for most is patch repairs in several different colours and failed coloured sealant that has split or peeled. Looking for mastic applicators who cover Stone? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Sealant jobs for businesses in a place the size of Stone are often best grouped: shopfront, washroom, kitchen and any external joints done together. That keeps travel and disruption down, and where colour matters on the frontage, we will confirm what’s available for the product.

A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or email the details over and we will come back to it.

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Why act early in Stone

Matching new joints to the existing ones is easier when the whole run is done together. Piecemeal repairs over several years tend to drift in colour. In a smaller place such as Stone, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • Constructionline member
  • Joints cleaned back to sound surfaces
  • Products installed to the manufacturer’s instructions
  • Colour options checked against the specified product

Questions we are asked in Stone

Is a smaller place like Stone outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Will our hotel in Stone need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.

Will the colour fade over time?

It can, to a degree. How much depends on the product, the colour and the exposure, so no colour stays exactly the same for ever.

Will the sealant be an exact match to our finish?

No, not always. We choose the nearest standard colour and a sample can be approved before the full run.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Stone has at least three named business or industrial parks inside a 3-mile radius.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Colour variation across natural stone or brick that no single shade can match
  • Overpainting a joint that needs a non-paintable product
  • Restoring stained stone or masonry next to old sealant

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

Surfaces we seal

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

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first, and our waste is bagged and taken away as we go. For a job in Stone, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.

  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. You approve the colour, on site if it’s critical.
  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.

What we need from you

  • Explain the parking and delivery arrangements
  • Let building users know which areas are affected
  • Make sure the joints can be reached

Getting a fixed quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Advice

What affects the price in Stone

The price varies from site to site. It mainly depends on:

  • Which sealant the job calls for
  • Location, for remote and island sites
  • Removal of failed or old sealant
  • Induction, permit and paperwork requirements

A quote for colour-matched joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

What we need to price the job

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

  • The product your specification calls for
  • Any dates the work must fit around
  • Access details, including height
  • Asbestos survey details if the building is older

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or send photos by email.
