How commercial sealant contractors works in OX28
Sealant joints are easy to overlook until one lets water in, and in an occupied building failure usually announces itself as a stained ceiling or an unhappy tenant. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in OX28. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. We work on washrooms and tea points, external facade joints and movement joints in walls and floors, and the usual reasons a site gets in touch are earlier reseals applied straight onto the failed bead and wall and floor joints that have lost their seal.
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us.
- 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.
Pricing in OX28
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why choose Mastic Doctor
- Standard and matched colours in many product ranges
- Colour options checked against the specified product
- Joints cleaned back to sound surfaces
- One contact handling all your sites

Commercial sealant contractors across OX28: the area picture
The commercial stock in OX28 mixes older town-centre buildings with newer offices and units, in places such as Witney, Cogges and Madley Park and beyond. Surfaces decide the sealant, from masonry to powder-coated frames and shop-fit panels.
All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, so jobs in OX28 are planned with access, loading and parking in mind.
Witney: If you have premises on more than one site, say at Eagle Industrial Estate and Windrush Valley Shopping Centre, one contractor and one quote can cover both. On estates like Eagle Industrial Estate (under half a mile south-east of Witney), the office and welfare end of each unit has its own sealant to maintain.
Site staff or a sealant specialist?
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. That’s why many clients bring in a specialist from the beginning.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Work for main contractors and building owners
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Common problems we fix in OX28
Resealing over the top is a false economy we come across often. New silicone has nothing to key into, so the top layer lifts, holds water and hides what’s going on. By the time it shows, there can be two or three layers to cut out.
Look out for the following:
- Black mould through washroom sealant that won’t clean off
- Messy, uneven beads from earlier work that let the building down
- A top-up bead over failed sealant, now lifting
- Expansion joints with the sealant torn out
Why deal with it now?
On many buildings the mastic was done by whichever trade was on site. Choosing the product, setting the depth and preparing the faces are what a specialist brings, and they’re where most failures begin. It shows over the following seasons rather than at handover.
What your quote should include
- How the joint faces will be prepared and primed
- Their plan for phasing and protecting the area
- Whether their applicators hold CSCS cards
- What level of public liability insurance do they hold?
Surface by surface
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.
Fire-rated seals where specified
Not every penetration suits a sealant. Other products, such as collars, wraps and batts, are specified for different services, and we will tell you if the detail calls for something else.
Questions we are asked in OX28
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Do you work directly for building managers?
Yes. You can send details through our quote form.
What site paperwork can you provide?
Send your site requirements with the enquiry, and we will confirm the RAMS, insurance and CSCS details with the quote. For older buildings we’ll ask for the asbestos register, plus your site induction rules.
How do you choose the sealant?
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.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Can one contractor look after sealant on all our buildings?
Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.
