About our coloured sealant in Old Coulsdon
Matching to anodised or powder-coated frames is a common request. The frame colour is checked against the sealant’s standard range, and you approve the choice. If the range has no close colour, a paintable sealant can sometimes be overpainted, where the specification allows. Site teams most often ask us about dirty, discoloured joints in public areas and fit-outs with a sealant colour in the specification, across office fit-out finishes, natural stone and brick and shop-fit joinery and counters. Searching for sealant specialists in Old Coulsdon? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. The right product goes on each, in a colour chosen to suit where the joint is seen.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Surface by surface
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.
Powder-coated and anodised frames
Window, door and shopfront frames in RAL colours often need a sealant to suit. The frame colour is checked against what the product is made in.
Diagnose, treat, sign off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. All of Greater London is in the ULEZ, and kerbside space in Old Coulsdon can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We confirm the joint type and the product it 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.
- We remove the masking and walk the finished joints with you.
What we need from you
- Tell staff and tenants when we will be in
- Explain the parking and delivery arrangements
- For older buildings, check the asbestos register before work

What Old Coulsdon’s businesses ask us to seal
In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. We work within them, one zone at a time. Less than 3 miles from Old Coulsdon there are two 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.
Old Coulsdon is inside London’s ULEZ, as is the rest of Greater London; tell us about loading bays, goods lifts and parking when you send details. For premises near Coulsdon South station, 1.4 miles to the north-west of Old Coulsdon, footfall is part of the plan: work is phased so shops and offices keep trading. A business with units at Ullswater Industrial Estate and Church Walk Shopping Centre needn’t use two contractors for its sealant.
Old Coulsdon is about 1 mile south-east of Coulsdon, in Greater London. Commercial clients in Old Coulsdon use us for work on colour-matched joints, as part of our coverage of Greater London. Our Greater London coverage takes in 764 places, large and small. Our London page has more on work in that area (14 miles or so).
Commercial sites across CR5, CR3 and CR8 are covered for colour-matched joints. If your site is on Ellis Road, Tollers Lane and Court Avenue or close by, send details and we’ll quote for colour-matched joints. Nearby places we also cover include Coulsdon (1 mile north-west), Chipstead (2 miles west), Purley (2 miles north), Woodcote (2 miles north-west) and Woodmansterne (3 miles west) for colour-matched joints. Further afield, our area takes in London (14 miles north), City of Westminster (15 miles north), Marylebone (15 miles north), Kensington (14 miles north), Whitechapel (15 miles north) and Brompton (14 miles north).
Around Old Coulsdon
We work on buildings around Sunnydown School, Dollypers Hill and The Tudor Rose pub. The closest station to Old Coulsdon is Coulsdon South station, roughly 1.4 miles north-west of the centre. Nearby you’ll also find East Surrey Museum (2 miles south-east) and St Lawrence's Hospital (1.3 miles south-east). Green spaces nearby include Nore Hill and Mercers Lake.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- A colour that never alters with age
- Overpainting a joint that needs a non-paintable product
- Materials with mixed tones that defy a single match
Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we will tell you honestly.
Surfaces we seal
- Natural stone and brick
- Shop-fit joinery and counters

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Building owners, agents and FMs in Old Coulsdon
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Old Coulsdon can form part of a wider programme across Greater London.
Why deal with it now?
It’s far cheaper to approve a sample than to strip and redo a full run. A sample takes little time against redoing a whole elevation. Getting scaffold, permits or access booked in Old Coulsdon takes effort, so it makes sense to deal with every failing joint while access is in place.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What you get with us

- Colours confirmed for the specified product

Old Coulsdon: questions and answers
Can the sealant on our Old Coulsdon premises match the finishes?
Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photographs and we will confirm what’s available for the product.
Do you cover business parks and estates near Old Coulsdon, such as Ullswater Industrial Estate?
Yes. Estates, retail parks and business parks around Old Coulsdon, Ullswater Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.
