Coloured sealant in Barnes Cray, done properly
Colour-matched joints are often among the last items before handover. Adjacent finishes are masked and protected while we work, and we leave the area clean. A 12-month guarantee covers our workmanship. We work on cladding panels, office fit-out finishes and natural stone and brick, and the failures we are asked to look at most are hotel refurbishments with a set colour scheme and patch repairs in several different colours. Looking for mastic applicators who cover Barnes Cray? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Buildings in a London area such as Barnes Cray rarely close for maintenance: occupied offices, ground-floor retail under residential floors and busy shared entrances. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Commercial clients in Barnes Cray
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Do you need coloured sealant in Barnes Cray?
Older sealant changes colour over time. Sunlight, dirt and pollution can darken, yellow or chalk the surface, and an old match drifts. Resealing is the chance to reset the colour.
Look out for the following:
- Shop fits that need consistent sealant colours across sites
- Weathered sealant that no longer matches
- Old colour-matched joints lifting at the edges
- White or grey sealant that clashes with the finish
In a retail centre such as Tower Retail Park, which lies south-west of Barnes Cray, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish.

From enquiry to sign-off
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. All of Greater London is in the ULEZ, and kerbside space in Barnes Cray can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we agree which sealant type the joint needs.
- We compare the target colour with the colours available.
- The nearest colour is agreed, with a sample bead where needed.
- The existing bead comes out, then faces are cleaned and backed.
- We mask, seal and tool to a clean line.
- We remove the masking and walk the finished joints with you.
Preparing the site
- Let building users know which areas are affected
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Cost factors for colour-matched joints
Quotes vary with the job. It mainly depends on:
- Induction, permit and paperwork requirements
- Which sealant the job calls for
- Removal of failed or old sealant
- Quantities, in metres or numbers
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
Details that help us quote
To price the job accurately, we need to understand the site. Useful things to include:
- Asbestos survey details if the building is older
- What the building is and how it’s used
- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
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 will fill any gaps with a visit.
Common questions from Barnes Cray clients
Must a hotel around Barnes Cray close while you work?
In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry.
Can the building stay open while you work?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
