Commercial sealant contractors for commercial buildings in Peckham
Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). We work on external facade joints, floor and threshold joints and washrooms and tea points, and the usual reasons a site gets in touch are frame mastic that has hardened and come away from the wall and earlier reseals applied straight onto the failed bead. Looking for mastic applicators who cover Peckham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Multi-site clients with buildings in and around Peckham can put several sites on one programme, so standards and paperwork match across every site.
Around Peckham, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email drawings and photos and we will come back to it.

How the job changes by surface
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.
Fire-rated seals where specified
Not every penetration suits a sealant. Other products, such as collars, wraps and batts, are specified for different services, so we’ll flag it if the detail needs a different product.

What else we do in Peckham
Why act early in Peckham
A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. Often the fitting is sound and the joint is the only thing letting it down. Resealing normally costs far less than renewal. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why choose Mastic Doctor in Peckham
- Over 20 years of commercial sealing
- Old sealant cut out, never sealed over
- Work carried out by CSCS-carded applicators
- Colours confirmed for the specified product

Working on commercial sites near Peckham
Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We plan around them and agree phasing so tenants and customers aren’t disrupted. There are two care or nursing homes within about 2 miles of Peckham. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean; colours can be chosen to suit the interior.
Shopping centres and retail parks such as Cantium Retail Park (to the north of Peckham) see a steady turnover of shop fits, each leaving joints where colour and finish matter. A hotel such as Peckham Rooms Hotel (to the north of Peckham) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Your questions answered
Will you take on work at estates like Astbury Business Park, close to Peckham?
Yes. We cover Peckham and the area around it, including industrial estates, business parks and retail parks such as Astbury Business Park. Send details of the unit and the work through our quote form for a quick quote.
Do you take on jobs in Peckham where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Is it OK to apply fresh sealant over existing beads?
Every failed bead is cut out completely. New sealant can’t grip the old bead, so laying over it never lasts, and the faces are brought back to sound, dry material before resealing.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Our process
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a job in Peckham, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- We hand back each area with its cure time and our 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Send asbestos survey details if the building is pre-2000
- Tell us which areas need to stay in use
Getting a fixed quote
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Keeping the joints sound
After handover, a little attention goes a long way:
- Don’t let cleaning or traffic back on before the cure time is up
- Put external and wet-area joints on a regular inspection round
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- On pre-2000 buildings, share the asbestos information before work starts
Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.
Sealant installed at the same time usually fails in sequence. A few splits this year typically mean more next year. We can assess the lot and suggest what to do now and later.
What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Suspect materials that need testing and specialist removal
- Walls or slabs moving more than any sealant can take
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
What we seal
- Floor and threshold joints
- Window and door perimeters
- Kitchen worktops and splashbacks
- Washrooms and tea points
- Movement joints in walls and floors
- External facade joints
Do you need commercial sealant contractors in Peckham?
A split down the middle of the bead tells a different story. Normally the movement was too much for the sealant chosen: a bead laid too thin, an over-stretched joint or the wrong movement class. Replacing it like for like rarely holds.
Typical triggers for a call:
- A top-up bead over failed sealant, now lifting
- Weathered facade sealant that no longer flexes
- Damp patches where an external joint has failed
- Shrunken sealant along kitchen worktops and splashbacks
Sites a few miles apart, such as Astbury Business Park and Bellenden Road Business Centre, can share one programme and one point of contact.
