Sealant specialists in Somerton
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and on a working site that typically surfaces as a leak, a stain or a complaint from occupiers. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. If you have movement joints packed with grit and debris and untidy joints in a reception, shop floor or lobby, we can help. Facilities teams, main contractors and managing agents in Somerton tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
We price commercial jobs in Somerton from photos, drawings or a site visit, and the scope is set out in writing.
Rural business units near smaller places such as Somerton are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Site staff or a sealant specialist?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
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.
After the work
For the best life from the joints:
- Check joints after other trades have worked nearby
- Don’t let cleaning or traffic back on before the cure time is up
- Note dates and locations of sealant work for future planning
- Make sure ventilation in wet areas is switched on and working
Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early. Should something look amiss, you can ring 01277 525 020 or email the details over and send a picture.
Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.
How the quote is worked out
Before we quote, we look at:
- The site’s rules and procedures
- The size and state of each joint
- Travel to remote or island sites
- How much existing material needs removing
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Different surfaces, different methods
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal, planned so the building keeps enough facilities in use.
Fire-rated seals where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps.
How a job runs
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Rural sites near Somerton may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- You send photos, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Before anything is cut out, we agree access, timings and sequence.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
What we need from you
- Move anything stored against the joints
- Tell staff and tenants when we will be in
- Send your site hours and access windows

Questions we are asked in Somerton
Can you work at a site such as Hatch End Old Industrial Estate, by Somerton?
Yes, sites like Hatch End Old Industrial Estate are within our area, along with the rest of Somerton. A few photographs and the unit address let us price the work.
Can the sealant on our Somerton premises match the finishes?
Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you work in Somerton?
Yes. Somerton is in our area and the rest of Oxfordshire, within our coverage of Greater London, South East England and Scotland. To discuss a job, phone 01277 525 020 or email drawings and photos.
Do you work for facilities managers and managing agents?
Yes. You send the details, we return a fixed quote, and the job is done and signed off.
Is failed sealant stripped out, or sealed over?
Full removal is part of every quote. Sealing over traps water and lifts once the joint moves.
What do you need from us to quote?
The main factors are metres of joint, removal, access, the product and how many phases there are. For a fixed quote, send details through our quote form.
Common problems we fix in Somerton
Washrooms and kitchens wear sealant out in their own way. Damp, harsh cleaning products and poor ventilation let mould take hold inside the bead. Replacement with a sanitary anti-mould silicone is the lasting answer.
Site and facilities staff are often the first to spot these:
- A top-up bead over failed sealant, now lifting
- Leaks that seem to come through a sealant line
- Expansion joints with the sealant torn out
- Gaps behind commercial kitchen worktops and sinks
Industrial estates such as Hatch End Old Industrial Estate, 2 miles south-west of Somerton, have offices, trade counters and welfare areas whose sealant ages like any other building’s.
