Commercial mastic work in Sutton
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. If you have gaps behind commercial kitchen worktops and sinks and window and door perimeter joints that have cracked open, we can put it right, on washrooms and tea points, external facade joints and window and door perimeters alike. A single leaking joint is often how a building in Sutton first comes to us: we look at the rest while we’re there and tell you what we find.
We price commercial jobs in Sutton from photos, drawings or a site visit, with the scope listed so everyone knows what’s included.
Commercial sealant work around smaller places like Sutton tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Leave it or put it right?
Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation, the three things that decide how long a joint lasts. It shows over the following seasons rather than at handover. Converted and older buildings near places like Sutton tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Check sealant as part of routine building inspections
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Make sure ventilation in wet areas is switched on and working
- Check joints after other trades have worked nearby
Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks, with external elevations and wet areas first in line. If anything looks wrong, speak to us on 01277 525 020 or use the quote form with a photo.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.
Common problems we fix in Sutton
A split down the middle of the bead tells a different story. Usually the movement was too much for the sealant chosen. Replacing it like for like rarely holds.
Look out for the following:
- Wall and floor joints that have lost their seal
- Damp patches where an external joint has failed
- Messy, uneven beads from earlier work that let the building down
- External beads that have gone brittle and cracked
A business with units at Lakeside Industrial Estate and Oakfields Industrial Estate needn’t use two contractors for its sealant.
What to look for in a quote
- How the joint faces will be prepared and primed
- What level of public liability insurance do they hold?
- Health and safety accreditation such as CHAS
- The named product and why it was chosen

When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Structural cracks or movement the joints weren’t designed for
- Faulty windows rather than failed perimeter sealant
- A failed roof covering or waterproofing membrane
Not sure which it is? You can call the office on 01277 525 020 or email us and we will tell you honestly before you book.

Common questions from Sutton clients
Can you match sealant colours for premises in Sutton?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.
Is Sutton too small for you to travel to?
No. Places such as Sutton are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
What site paperwork can you provide?
Send your site requirements with the enquiry, and we will confirm the RAMS, insurance and CSCS details with the quote. From you, we will need the asbestos information for older buildings and any site rules.
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.
What guarantee do you give on resealing?
It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
