Commercial sealant contractors in SO16: how it works
Mastic Doctor has been sealing joints for businesses and contractors since 2005: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. Most enquiries involve weathered facade sealant that no longer flexes and messy, uneven beads from earlier work that let the building down, on floor and threshold joints, external facade joints and washrooms and tea points.
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it.
- We start with the evidence: photos, drawings or a look on site.
- 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.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.

Landmarks near Maybush
We work on buildings around St Peter's Church, St James' Park and Millbrook Community School and the streets around them. Nearby too are Bridge Tavern (under half a mile north-east), Newlands Primary School (less than half a mile south-west) and Regents Park Community College (0.7 miles south-east). Maybush’s nearest station is Redbridge station, about 1.2 miles south-west. Nearby you’ll also find Eling Experience (1.8 miles south-west) and Western Community Hospital (less than half a mile south). Not far away are Testwood Lakes.
Commercial premises across SO16
In SO16, much commercial sealant work follows refits in shops, offices and hotels in places such as Shirley, Regents Park and Maybush. Visible joints call for a matched colour and a clean tooled finish.
All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, so jobs in SO16 are planned with access, loading and parking in mind. Coastal places in SO16 often have hotels, guest houses and holiday accommodation with busy seasons, which makes the quieter months a good time for sealant work.
Maybush: In hotels such as Anchor Hotel, which lies south-west of Maybush, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. A unit on an estate like Northbrook Industrial Estate, 1 mile east of Maybush, normally has an office front, a trade counter and staff facilities with joints of their own.
Doing it in-house
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Make sure contractors see the asbestos survey before cutting out old mastic
- Keep barriers up until the new sealant has cured
- Keep a record of which joints were resealed and when
- Check joints after other trades have worked nearby
Give fresh sealant time to cure before it’s cleaned, wetted or walked past. Cure time varies with the product, conditions and depth of the joint, so we confirm it for each area at handover. Keeping signs or barriers up until then protects the finish.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are, so sound, smooth joints matter.
How the job changes by surface
Commercial kitchens and tea points
In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. Proper degreasing comes before any new sealant, and a hygienic or food-safe sealant is used where food contact is possible.
Movement joints in walls and floors
Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. Failed seals let grit and water in, and the edges start to suffer. The joints are resealed using a sealant matched to the movement and any traffic.
Quoting for work in SO16
Quotes vary with the job. It mainly depends on:
- Which sealant the job calls for
- Phasing around occupants
- The size and state of each joint
- Distance, for remote addresses
A quote for sealant joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.
Before you send an enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Access details, including height
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
- The asbestos register, for older buildings
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Common problems we fix in SO16
Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. On a busy commercial site several of those pile up at once, which is why regular inspection pays.
Look out for the following:
- Sanitary sealant that has gone black and patchy
- Frame mastic that has hardened and come away from the wall
- External beads that have gone brittle and cracked
- A top-up bead over failed sealant, now lifting
Your questions answered
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
How many days will you need on site?
It depends on the scope, though a typical visit usually takes a few hours to several days on most single sites, depending on joint lengths and access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
What site paperwork can you provide?
Let us know your requirements when you ask for a price, and we’ll 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.
How do we get a quote?
Send photos, drawings or a list of locations. If a visit is needed we’ll book one, and a fixed quote follows.
Is the old sealant taken out first?
The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
