What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Suspect materials that need testing and specialist removal
- Water from a services leak rather than a joint
- Roof leaks that only look like a joint problem
If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

About our commercial sealant contractors in Oakhanger
We have applied sealant on commercial sites for over 20 years: 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 will confirm with the quote. We work on external facade joints, washrooms and tea points and movement joints in walls and floors, and the failures we are asked to look at most are frame mastic that has hardened and come away from the wall and untidy joints in a reception, shop floor or lobby. Searching for sealant specialists in Oakhanger? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
A lot of what we do in Oakhanger is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
In and around smaller places such as Oakhanger, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes anything from part of a day on a short run of joints to several weeks on a large phased package. For a building around Oakhanger, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings
- Point out parking and an unloading spot

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email the details over to discuss it first.
Advice
When to call us in Oakhanger
Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath so it soon peels and traps moisture against the joint. Getting back to a clean joint then means removing every layer.
If one of these sounds familiar, it’s time for a closer look:
- Mouldy silicone around WCs, urinals and vanity tops
- Wall and floor joints that have lost their seal
- Frame sealant that has cracked, shrunk or pulled away
- Earlier reseals applied straight onto the failed bead
Trade counters and showrooms on estates such as Southlands Industrial Park (to the south of Oakhanger) need neat joints where clients see them.

Questions we are asked in Oakhanger
Do you offer colour-matched sealant for buildings in Oakhanger?
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 Oakhanger too small for you to travel to?
Not at all. Oakhanger is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
Can areas stay open during the work?
Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.
Is the old sealant taken out first?
Removal of the failed sealant is always part of the job. New sealant can’t grip the old bead, so laying over it never lasts, and the faces are brought back to sound, dry material before resealing.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Different surfaces, different methods
Fire-rated seals where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. Fire-stopping design and sign-off sit with the designer, fire engineer or building control; we install what’s specified.
Facade and cladding joints
Panel joints on cladding and rendered facades open and close with the temperature. The product has to suit the movement, and the depth has to be controlled with backing. Access, such as scaffold already up, is agreed before the price is fixed.
Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
