Construction mastic for Cothill sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
On site: what to expect
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Cothill need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Confirm the product named in the specification
- Share your working hours and any access restrictions
Request a quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Construction mastic in Cothill, done properly
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. If you are dealing with different trades sealing to different standards and mastic snags holding up handover, we can put it right, on brick and block movement joints, floor and skirting junctions and window and door perimeters alike. Facilities teams, main contractors and managing agents in Cothill tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Construction in and around smaller places such as Cothill is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
A 12-month guarantee applies to all our work in Oxfordshire. Should something we installed fail, give us a call on 01277 525 020 or email drawings and photos and we’ll come back to it.

What the job involves on each surface
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control and we install what’s specified.
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. A neat, consistent caulk line makes the decorators’ job quicker and keeps the snag list down.
Questions we are asked in Cothill
Will you plan work around the academic year at somewhere like McTimoney Chiropratic College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on work at healthcare sites like Abingdon Community Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you work while the building is occupied?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
Do your applicators hold CSCS cards?
Our applicators hold CSCS cards, and we’re CHAS accredited and a Constructionline member. Public liability insurance of five million pounds is in place too.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Frame gaps too wide for sealant, which the installer needs to correct
- Designing joint widths or choosing the specification (that sits with the designer)
If you are not sure, just phone 01277 525 020 or send photos by email and we will give you a straight answer before you book.
What we seal
- Window and door perimeters
- Cladding and panel joints
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Floor and skirting junctions
- Brick and block movement joints
Why act early in Cothill
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference, especially externally. Where an alternative is genuinely suitable, we’ll say so. One visit to deal with every failing joint makes more sense than several trips to a place like Cothill, rather than one at a time. Send photos of each area and we’ll quote for the lot.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Quoting for work in Cothill
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Which sealant the job calls for
- Whether old sealant has to be cut out first
- Working within restricted access windows
- Quantities, in metres or numbers
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
Sending details for a quote
To price the job accurately, we need a clear picture of the site. Send us:
- How the joints are reached, and at what height
- The site address and postcode
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Contractors’ notes for Cothill
Central London is about 55 miles from Cothill. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. A number of hotels sit less than 2 miles from Cothill. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
Further education sites such as McTimoney Chiropratic College, 1.8 miles to the south-east of Cothill, are extended and refurbished from time to time, with mastic often programmed into the summer break. New wings at hospitals like Abingdon Community Hospital, 2 miles south-east of Cothill, bring long runs of window and panel joints to seal. When units on a site such as Wootton Business Park (1.3 miles north of Cothill) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
