Common questions from Duncton clients
Which documents can you supply for work in Duncton?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Can the sealant on our Duncton premises match the finishes?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.
Can weather delay the job?
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. Internal work is rarely affected.
Is Duncton in your area?
Yes. Duncton falls within our area, and the simplest way to start is to call 01277 525 020 or email us.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
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 your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards.
Coloured sealant in Duncton
Where finishes matter, a white or grey bead in the wrong place stands out. Our coloured sealant work blends joints into the surrounding materials, from powder-coated frames to stone and brick. Performance decides the product; the colour is chosen from that product’s range. Site teams most often ask us about untidy coloured beads with ragged edges and colour changes after a rebrand or refit, across natural stone and brick, office fit-out finishes and powder-coated and anodised frames. Facilities teams, main contractors and managing agents in Duncton tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In and around smaller places such as Duncton, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a day for a modest shop fit, and longer for a full building or several floors, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Duncton are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we agree which sealant type the joint needs.
- Your RAL reference, sample or photo is checked against that product’s colours.
- You approve the colour, on site if it’s critical.
- We cut out the existing bead, clean and set the depth.
- Edges are masked and the coloured sealant applied and tooled.
- We remove the masking and walk the finished joints with you.
Preparing the site
- Confirm the product named in the specification
- Move anything stored against the joints
- Flag any permit to work we will need

Advice
Should maintenance staff do it?
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
Common problems we fix in Duncton
A coloured joint can fail like any other: splits, adhesion loss and hardening all happen. The fix is a full cut-out and a new bead in the right colour.
If one of these sounds familiar, it’s time for a closer look:
- Sealant that no longer suits recoated frames
- Patch repairs in several different colours
- Stained or mouldy coloured joints in washrooms
- Coloured joints that have cracked with movement
Whatever the building in Duncton, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- The terms of the workmanship guarantee
- Is the sealant right for the movement and the substrate?
- Whether old or failed sealant will be cut out, not overlaid
Different surfaces, different methods
Office fit-outs
Partition frames and joinery are often in a set colour. We match from the product’s range and agree them before work starts.
Shop-fit and joinery finishes
In shops, joints are at eye level and inspected by clients. A sharp, even bead is as important as the colour.
Sealant on show in Duncton’s commercial buildings
Rainfall across the South East, Duncton included, is lower than in many parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. At about 45 miles from central London, Duncton is within reach of the capital. The commuter belt holds a great many offices, retail parks and business parks. Firms with branches across the South East can use one contractor for every site.
Colour matters on frontages and fit-outs, so the quote confirms which colours the chosen product comes in.

What affects the price in Duncton
The price varies from site to site. It mainly depends on:
- Backing rod, priming and other preparation
- Location, for remote and island sites
- The product specified
- Removal of failed or old sealant
Pricing colour-matched joints depends on how many there are, their condition and the access. 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:
- Specification clauses that apply
- Drawings or a marked-up plan, if available
- The type of building and who uses it
- Whether an asbestos survey exists
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email us with what you know.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Record the product and colour reference on the building file
- Don’t let trades patch coloured joints with a random sealant
- Avoid piecemeal repairs on coloured joints
- Use one colour standard across multi-site work
Don’t let anyone patch a coloured joint with whatever sealant is to hand. A mismatched repair stands out.
Ask for a trial bead on high-profile areas. A sample in real light shows how it will look.
