Your questions answered
Can you work at a site such as Wychwood Business Centre, by Ascott Earl?
Yes. Estates, retail parks and business parks around Ascott Earl, Wychwood Business Centre among them, are all within reach. A few photos and the unit address let us price the work.
Is Ascott Earl off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
What do you charge?
There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Expansion joint sealing in Ascott Earl
Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. If you are dealing with car park joints leaking onto vehicles below and chipped joint edges on forklift routes, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Ascott Earl it comes down to the same thing: the right product in a properly prepared joint.
Halls, schools and small commercial buildings near places like Ascott Earl have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
Every job we finish is backed by a 12-month workmanship guarantee, in Ascott Earl as everywhere else we work. If our installation lets you down in that time, we return and fix it.

General trades versus a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
How the quote is worked out
A fixed quote reflects the actual work. It takes account of:
- The site’s rules and procedures
- Travel to remote or island sites
- Any access equipment needed
- The product specified
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What we need to price the job
A few photos plus some basic facts will normally do. Please tell us:
- Where the site is, with the postcode
- Anything awkward about access or site hours
- The asbestos register, for older buildings
- Specification clauses that apply
For a fixed quote, call the office on 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. You can also send details through our quote form.
Our process
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Ascott Earl, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- We strip out the old seal and prepare the faces.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.
Preparing the site
- Point out any areas we must not close
- Clear stock, furniture or equipment away from the joints
- Flag any permit to work we’ll need

Why act early in Ascott Earl
Spot repairs can be useful on a tight budget. But if the rest of the run is the same age and product, it’s typically not far behind and repeated access costs add up. We can price a patch and a full reseal side by side. One visit to deal with every failing joint makes more sense than several trips to a place like Ascott Earl. Photos of every joint help us quote for the whole job.
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.
Why us?
- A fixed quote before work starts
- RAL and finish matching where the product range allows
- One number for every site we cover
- Public liability insurance in place

Surface by surface
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.
Do you need expansion joint sealing in Ascott Earl?
When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again.
Most enquiries start with something like this:
- Rain penetration at brick or block movement joints
- Sealant pulling off the joint face
- Hardened, cracked sealant on exposed facades
- Water dripping through deck or ramp joints
Business parks such as Wychwood Business Centre, 1.4 miles to the west of Ascott Earl, have car parks, paved areas and long brick and panel elevations, all with movement joints.
