How we handle coloured sealant in New Eltham
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 before we quote. An exact bespoke match can’t always be promised, so we talk you through the nearest colours. If you have sealant that no longer suits recoated frames and coloured joints that have cracked with movement, we can help, whatever the surface. Looking for mastic applicators who cover New Eltham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Around New Eltham, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Coloured sealant in New Eltham: the local picture
Less than 3 miles from New Eltham there are at least three named estates and business parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints, often in a colour the occupier specifies. Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. We plan around them and agree phasing so tenants and customers aren’t disrupted.
Access in New Eltham needs thought: the ULEZ covers all of Greater London, and loading and parking are rarely simple. For a hotel such as The Eltham Hotel, which lies north of New Eltham, the colour of a joint at the bar or the bath matters to the look of the room.

Building owners, agents and FMs in New Eltham
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
What sets the cost
The price varies from site to site. It mainly depends on:
- Specialist products, such as fire-rated or hygienic sealants
- The site’s rules and procedures
- Removal of failed or old sealant
- Joint width, depth and condition
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Any specification or named product
- Where the site is, with the postcode
- Access details, including height
- Whether the building will be occupied during the work
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
What we’re called out for in New Eltham
When frames are recoated or a space is rebranded, the old joints may no longer suit. Refurbishments and rebrands often bring a new colour scheme that the sealant has to follow.
Things that normally lead to an enquiry:
- Previous reseals that don’t match the original
- Dirty, discoloured joints in public areas
- Hotel refurbishments with a set colour scheme
- Smeared sealant on stone or joinery
Occupiers with premises at both Green Lane Business Park and Chiltonian Industrial Estate could have the sealant at each handled under one quote.

- Who will actually carry out the work
Why act early in New Eltham
A failed joint lets in water and dirt, whatever colour it is. Behind the bead, moisture can damage substrates and finishes, so resealing protects the finishes as well as the look. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

How a job runs
When we get to site, 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 any cutting starts, with the work itself typically taking about the same time as any other sealant work, plus a little longer if a sample bead is agreed first. For a job in New Eltham, access comes first. Send the building rules and access times with your enquiry.
- First we agree which sealant type the joint needs.
- Your RAL reference, sample or photo is checked against that product’s colours.
- 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.
- Masking comes off and the work is checked with you.
What we need from you
- Let us know about inductions and permits
- Send your site hours and access windows
- Send any specification or drawings in advance
Ask for a quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Questions about New Eltham
Do you take on jobs in New Eltham where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Do hotels near New Eltham have to close for sealant work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we’ll plan around them.
Do you cover New Eltham?
Yes. We cover New Eltham, within our coverage of Greater London, South East England and Scotland. For a quote, phone 01277 525 020 or send photos by email.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Do you use coloured sanitary silicone?
Yes. Wet-area sealants are made in colours as well as white. We check the colour range of the sanitary product specified.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Doing it in-house
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
