Your questions answered
Is Sandford Lane Industrial Estate, near Kennington, within your area?
Yes. Estates, retail parks and business parks around Kennington, Sandford Lane Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Is Kennington off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Do you check for asbestos before removing sealant?
On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder and removing it isn’t something we do.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Does commercial sealant work come with a guarantee?
The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Sealant applicators in Kennington
How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Primer is used wherever the manufacturer calls for it on that surface, and a backing rod limits the depth to give the sealant room to work. We work on floor and threshold joints, window and door perimeters and movement joints in walls and floors, and the usual reasons a site gets in touch are hardened, chalky sealant on south-facing or exposed elevations and wall and floor joints that have lost their seal. One point of contact handles commercial sealant work in Kennington from the first photos to the final walk-round, whether it’s one building or several.
On a typical commercial building in Kennington, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
Places like Kennington tend to have a handful of commercial buildings: a local shop, a pub or restaurant, a surgery, a school and the odd office or workshop. Each job is modest, yet a joint in a small café needs the same cutting out, cleaning and sealing as one in a city office.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Commercial premises in Kennington
Kennington lies roughly 51 miles out from central London. This part of the South East is dense with business parks and out-of-town offices. Multi-site occupiers here often want one sealant contractor across all their buildings. Kennington is in the South East, one of the UK’s drier regions. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.
Occupiers with premises at both Sandford Lane Industrial Estate and The Oxford Science Park could have the sealant at each handled under one quote. In hotels such as Oxford Thames Hotel, 0.6 miles to the east of Kennington, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. If you run a unit on an estate such as Sandford Lane Industrial Estate, 0.5 miles south-east of Kennington, the trade counter, offices and staff facilities have joints to look after as well as the warehouse.
Kennington is about 3 miles south of Oxford, in Oxfordshire. Across the OX1 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 423 places in Oxfordshire, from busy centres to rural villages.
Work on sealant joints is covered throughout OX1 and OX14, for business premises of every kind. For a building on Simpsons Way, The Avenue and Liddiard Close or nearby, send details and we will quote for sealant joints. Just outside Kennington, we also work in Sandford-on-Thames (1 mile east), Littlemore (1 mile north-east), Redbridge (1 mile north), Hinksey Hill (1 mile north-west) and Bayworth (1 mile west). Bigger towns within reach include Oxford (3 miles north), Didcot (7 miles south), Bicester (14 miles north), Abingdon-on-Thames (3 miles south-west), Witney (12 miles north-west) and Carterton (15 miles west).
Around Kennington
We work on buildings around The Oxford Academy, Emmanuel Christian School and The Tandem pub and the streets around them. For rail, the closest station is Radley station, roughly 1.8 miles south of the centre. A little further out are Templars Square (1.9 miles north-east) and Oxford Castle and earlier settlement remains (2.9 miles north). For a walk, there’s Lashford Lane Fen and Harcourt Hill.
Quoting for work in Kennington
The price varies from site to site. It mainly depends on:
- How much there is to seal
- Access and working height
- How much existing material needs removing
- Whether the work must be split into stages
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
What to include in your enquiry
The more we know, the firmer the quote. Helpful details to send:
- The site address and postcode
- The product your specification calls for
- Clear photos of the problem areas
- The asbestos register, for older buildings
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or use the quote form if you’d rather talk the job through.
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Why deal with it now?
Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. If neighbouring businesses or buildings around Kennington need work too, visits can be combined. Tell us your site hours and we will plan around them.
- We begin with whatever information you have, whether that’s photos, a drawing or a list of locations, or we arrange a site visit.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Site hours, access windows and the order of areas are agreed before we start.
- We strip the failed bead and prepare both faces of the joint.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- For older buildings, check the asbestos register before work
- Arrange parking or a loading space
Get a fixed quote

Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Report cracked or peeling sealant early
- Keep washroom and kitchen extraction working
- Look at the sealant around anything that has been moved or replaced
- Respect the cure time before reopening an area
Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet, and mould follows damp. It’s worth having fans checked while the sealant is fresh.
Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.
Honest limits
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Water from a services leak rather than a joint
- Walls or slabs moving more than any sealant can take
- Roof leaks that only look like a joint problem
If in doubt, ring 01277 525 020 or send photos by email and we will say what we think before you book.
