Coloured sealant in Petersham, done properly
We can agree a short trial length before the full run. Sealant can look slightly different once it has cured, and again in different light. Let us know who signs off colour, and we’ll fit the sample into the programme. We work on shop-fit joinery and counters, cladding panels and natural stone and brick, and the usual reasons a site gets in touch are white or grey sealant that clashes with the finish and dirty, discoloured joints in public areas. Searching for sealant specialists in Petersham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the colour-matched joints are resealed in sections so tenants are disturbed as little as possible.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Different surfaces, different methods
Shop-fit and joinery finishes
Counters, display units and wall linings are seen close up. A sharp, even bead is as important as the colour.
Brick and masonry
Brickwork joints normally look best in a colour close to the mortar or brick. The nearest colour in the range is agreed with you.
When to call us in Petersham
When frames are recoated or a space is rebranded, the old joints may no longer suit. New cladding colours, repainted frames or a refreshed shop fit all prompt colour changes.
Any of the following is a good reason to get the joints checked over:
- Sealant that no longer suits recoated frames
- Patch repairs in several different colours
- Discoloured joints on a visible elevation
- Failed coloured sealant that has split or peeled
In hotels such as The Petersham Hotel, under half a mile north-east of Petersham, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Sealant on show in Petersham’s commercial buildings
Petersham has at least three named business or industrial parks inside a 3-mile radius. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it. Petersham has plenty of hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, and the work can be phased so the rest of the hotel keeps trading.
Trade counters and showrooms on estates such as St. George's Industrial Estate, 1.2 miles south of Petersham, need neat joints where customers see them. Shopping centres and retail parks such as Ivybridge Retail Park (1.5 miles north-west of Petersham) see a steady turnover of shop fits, each leaving joints where colour and finish matter.

First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off.

Send the building rules and access times with your enquiry.
- 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.

Related advice
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Agree the sealant colour early and write it into the specification
- Keep the area clear while the sealant cures
- Standardise colours across a portfolio
- Check a trial length in real light
Use gentle cleaning methods on coloured sealant. Strong solvents and abrasive pads can dull or mark the surface.
Put the sealant colour into the specification or finishes schedule. When colour is left to the last minute, it is often wrong, so agree it with the designer at the start.
