Construction mastic in Fritwell
Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We work on floor and skirting junctions, internal decorators’ caulk and sanitary and kitchen joints, and what we’re called in for most is snag items on joints that need redoing before handover and perimeter gaps outside the sealant’s range. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Fritwell it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In the countryside around places like Fritwell, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What we’re called out for in Fritwell
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.
If one of these sounds familiar, it’s time for a closer look:
- Caulk cracking where joints are moving more than expected
- External joints sealed in damp or cold conditions that are now failing
- Missed perimeter joints on a new elevation
- Inconsistent sealant finishes from plot to plot
Extensions at sites like Bicester Community Hospital, 5.4 miles to the south-east of Fritwell, typically sit beside working departments, and the mastic follows strict access rules.
Before you book anyone
- Which product they’ll use, and why it suits the joint
- What level of public liability insurance do they hold?
- How joint depth will be controlled
- Will RAMS and insurance details be available?
Mastic packages on Fritwell sites
Fritwell is about 58 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.
When a school such as Fritwell Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. New units and refits on sites such as Baynards Green Trading Estate (to the east of Fritwell) need their panel and perimeter joints sealed to the specification.

Why it’s worth doing now in Fritwell
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility, with the same standard on every plot. One visit to deal with every failing joint makes more sense than several trips to a place like Fritwell. Send photos of each area and we will quote for the lot.
Pricing mastic packages depends on how many there are, their condition and the access. Call for a quote.

Doing it in-house
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Cost factors for mastic packages
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Whether old sealant has to be cut out first
- The site’s rules and procedures
- Whether the work must be split into stages
- Joint width, depth and condition
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.
Before you send an enquiry
A few photos plus some basic facts will normally do. It helps to include:
- The site address and postcode
- Rough lengths or quantities, or drawings if you have them
- The product your specification calls for
- Asbestos survey details if the building is older
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email a schedule or drawings.
Common questions from Fritwell clients
Is Fritwell off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Is a hospital such as Bicester Community Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
How much does the work cost?
Every job gets its own fixed quote. To get one, phone 01277 525 020 or email a schedule or drawings with a description of the work.
Is the mastic package guaranteed?
The work is guaranteed for 12 months. Keeping other trades off finished joints prevents most problems.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Does weather affect external mastic work?
Weather matters for external sealing: the joint needs to be dry and within the product’s temperature range. External work is sequenced with some flexibility.
What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Glazing units that are cracked or misted
- Specifying the product where the designer hasn’t
- Damage to finishes by other trades after we have sealed
If you’re not sure, just ring 01277 525 020 or send photos by email and we will give you a straight answer before you book.
What we seal
- Cladding and panel joints
- Sanitary and kitchen joints
- Floor and skirting junctions
- Brick and block movement joints
- Window and door perimeters
- Internal decorators’ caulk
