Coloured sealant near Mountain Street

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Surface by surface

Brick and masonry

On brick, the sealant often matches the mortar rather than the brick face. The nearest colour in the range is agreed with you before work starts.

Natural stone

Natural stone rarely has one colour, and the sealant has to work with that. A stone-safe neutral-cure product is used in a colour chosen from its range.

Coloured sealant for commercial buildings in Mountain Street

Colour is often written into the specification, by RAL reference or by matching a sample. Standard sealant ranges cover many colours, so we check what the specified product is made in at quote stage. An exact bespoke match can’t always be promised, so we talk you through the nearest colours. We work on hotel bathrooms and public areas, powder-coated and anodised frames and cladding panels, and what we’re called in for most is standard-colour sealant spoiling a high-end finish and failed coloured sealant that has split or peeled. Looking for mastic applicators who cover Mountain Street? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

A job in a smaller place like Mountain Street is typically a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Leave it or put it right?

Across a chain of shops or hotels, consistency matters. Setting one product and colour for every site avoids variation. For buildings around smaller places like Mountain Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why appoint us

  • One number for every site we cover
  • Matching to RAL references, product permitting
  • Workmanship guaranteed for 12 months
  • Over 20 years of commercial sealing

Coloured sealant in Mountain Street: the local picture

Mountain Street lies roughly 49 miles out from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Occupiers with several premises in the region tend to prefer one contractor and one point of contact. Rainfall across the South East, Mountain Street included, is lower than in many parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.

Premises within reach of Chilham station (0.8 miles north-east of Mountain Street) often have busy frontages where joints are seen by everyone passing.

Mountain Street is about 6 miles south-west of Canterbury, in Kent. Anywhere in CT4, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 931 places in Kent. For work in that direction, see our London page.

Commercial sites across CT4 are covered for colour-matched joints. Sites close to Mountain Street are covered too, including Chilham (1 mile north-east), Godmersham (1 mile south), Old Wives Lees (1 mile north), Shottenden (2 miles north-west) and Bilting (2 miles south). A short drive away, we cover Ashford (8 miles south-west), Canterbury (6 miles north-east), Sittingbourne (12 miles north-west), Folkestone (14 miles south-east), Whitstable (9 miles north) and Faversham (6 miles north-west).

Common problems we fix in Mountain Street

Failed sealant still has to be dealt with, whatever its colour: splits, adhesion loss and hardening all happen. We cut out and reseal in the agreed colour.

Any of the following is a good reason to get the joints checked over:

  • Coloured joints that have cracked with movement
  • Dirty, discoloured joints in public areas
  • Joints that need to match a new RAL frame colour
  • Shop fits that need consistent sealant colours across sites

Whatever the building in Mountain Street, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Comparing quotes

  • What level of public liability insurance do they hold?
  • What site paperwork they can supply
  • Do they follow the manufacturer’s priming guidance?
  • Which product they’ll use, and why it suits the joint

Our contractor checklist

How a job runs

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking a few hours or a phased programme, depending on joint lengths and how many colours are involved. For a building around Mountain Street, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. Photos or drawings show us the finishes and joints.
  2. We send the closest colours from the product’s range.
  3. The programme and access are agreed, including any phasing.
  4. Joints are prepared, primed where specified and backed.
  5. The agreed colour is installed and tooled neatly.

Before we start on site

  • Move anything stored against the joints
  • Let building users know which areas are affected
  • Confirm the product named in the specification

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Agree the sealant colour early and write it into the specification
  • Keep the area clear while the sealant cures
  • Ask contractors to check the colour before resealing
  • Keep the same sealant colour across a brand

Expect some change in appearance over the years. That is normal for exposed sealant, and a reseal brings it back.

Plan resealing of visible joints before they look tired. Replacing them on a schedule keeps finishes looking right.

Common questions from Mountain Street clients

Is Mountain Street too far out for you?

Not at all. Mountain Street is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

What documents will you need to give us for a job in Mountain Street?

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

Do you work on hotel and retail fit-outs?

Yes. We work with shop fitters, hotel groups and office fit-out contractors. Our area takes in Greater London, the South East and Scotland.

Can we specify the colour by RAL number?

Yes. We compare the RAL reference with the colours made for the specified sealant. We’ll tell you which colour is closest.

Will the colour fade over time?

Exposed sealant can change in appearance over the years. Sunlight, dirt and weathering affect how it looks, and resealing brings the look back.

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
