How commercial sealant contractors works in SM6
Mastic Doctor has been sealing joints for businesses and contractors since 2005: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. We work on external facade joints, floor and threshold joints and window and door perimeters, and the usual reasons a site gets in touch are wall and floor joints that have lost their seal and hardened, chalky sealant on south-facing or exposed elevations.
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Pricing in SM6
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Commercial sealant contractors across SM6: the area picture
In SM6, much commercial sealant work follows refits in shops, offices and hotels in places such as Carshalton, The Wrythe and Wallington. Where the joint is on show, a colour that suits the finish is part of the job.
The South East is one of the UK’s drier regions, but external sealing in SM6 still needs a dry joint and the right temperature, and damp or frosty mornings can hold it up.
Wallington: A business with units at Anchor Business Park and Silver Wing Industrial Estate needn’t use two contractors for its sealant. For premises near Wallington station, which lies south of Wallington, footfall is part of the plan: work is phased so shops and offices keep trading.
What affects the price in SM6
We price every job individually. The main factors are:
- Phasing around occupants
- Quantities, in metres or numbers
- The product specified
- Any access equipment needed
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Before you send an enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- Where the site is, with the postcode
- Drawings or a marked-up plan, if available
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. If you have questions first, ring 01277 525 020 or use the quote form.
Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
How the job changes by surface
Shop fronts and retail fit-outs
Retail work typically has to fit around trading. Tell us your trading hours and access windows and we’ll plan around them, phasing areas so the shop floor stays usable.
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean. We seal to a neat, cleanable finish and work around service times you agree with us.
Leave it or put it right?
On many buildings the mastic was done by whichever trade was on site. Choosing the product, setting the depth and preparing the faces are what a specialist brings, the three things that decide how long a joint lasts. You notice the difference years later, not on the day.
Questions to ask before you book
- How they handle RAMS and site documents
- Whether primer will be used where the manufacturer specifies it
- Will failed sealant be removed rather than covered?
- Their public liability cover
Common problems we fix in SM6
A split down the middle of the bead tells a different story. That usually means the joint stretched further than the product could cope with because the bead was too thin, the joint over-stretched or the movement class wrong. The same product in the same joint tends to fail the same way, so width, depth and product are checked before we quote.
Common reasons buildings call us in:
- Water staining near frames, panels or ceilings
- Frame sealant that has cracked, shrunk or pulled away
- Mouldy silicone around WCs, urinals and vanity tops
- Messy, uneven beads from earlier work that let the building down
FAQs: SM6
Can you handle sealant work across several sites?
Yes. Give us the sites and the scope at each, and fixed prices follow, with a suggested sequence.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Is SM6 in your area?
Yes. Sites across SM6 are covered.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, which many sites require.
Do you check for asbestos before removing sealant?
On older buildings, our first request is the asbestos survey. Managing asbestos is the dutyholder’s responsibility.
Can you take on work for an FM or managing agent?
Yes. A large share of our work comes through facilities managers, managing agents and landlords. Tell us how you issue work and we’ll fit in.
