Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price 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 typically costs more in the end than doing them right.
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.
Construction mastic in North Leigh, done properly
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place. We work on brick and block movement joints, floor and skirting junctions and window and door perimeters, and what we are called in for most is external joints sealed in damp or cold conditions that are now failing and different trades sealing to different standards. Looking for mastic applicators who cover North Leigh? We have been sealing commercial buildings since 2005.
Sites around smaller places like North Leigh can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or send photos by email and we’ll come back to it.

FAQs: North Leigh
Is North Leigh off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Could you schedule work at a campus like Abingdon & Witney College: Witney Campus for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Do you seal on top of existing 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.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How do we ask for a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Do you guarantee new-build sealant work?
Our workmanship carries a 12-month guarantee from sign-off. Damage by others after we have finished isn’t covered.
Work for main contractors and building owners
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Why act early in North Leigh
Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. Sealant can’t grip a contaminated or existing bead. Damaged joints are removed and resealed from clean faces. For buildings around smaller places like North Leigh, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
Why appoint us
- Coloured sealants to suit the setting, where available
- One number for every site we cover
- Fully insured
- Joints cleaned back to sound surfaces
When something else is needed
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Frame gaps too wide for sealant, which the installer needs to correct
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Joint design decisions that belong to the architect or engineer
If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think.
Joints and surfaces we work on

Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around North Leigh, 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.

Advice
Construction mastic around North Leigh: points for this area
Central London is about 62 miles from North Leigh. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. North Leigh is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.
With historic properties like Blenheim Palace (to the north-east of North Leigh) in the area, refurbishment work often meets old masonry that needs compatible sealants. When a college such as Abingdon & Witney College: Witney Campus, 2.8 miles to the south-west of North Leigh, builds or refurbishes, the mastic package normally has to fit around students and staff. Recladding or extending a unit at a site like Northleigh Business Park, 0.5 miles to the east of North Leigh, brings panel joints and frame perimeters into the programme.

Snagging before handover
The last pass before handover is where mastic snags are cleared. Snags are cleared room by room and damaged joints are redone rather than patched.
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used.
