Construction mastic for Ascott d'Oyley sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How the job changes by surface
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
How we handle construction mastic in Ascott d'Oyley
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. We work on window and door perimeters, brick and block movement joints and sanitary and kitchen joints, and the usual reasons a site gets in touch are oversized or tapered gaps around new frames and external joints sealed in damp or cold conditions that are now failing. Most enquiries from Ascott d'Oyley start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For a site near Ascott d'Oyley, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we’ll quote to suit.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Do you need construction mastic in Ascott d'Oyley?
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
It’s worth sending us details if you spot any of the following:
- External joints sealed in damp or cold conditions that are now failing
- Old sealant on a refurbishment that needs stripping before new work
- A mastic package split between trades with no clear owner
- Oversized or tapered gaps around new frames
Historic houses such as Minster Lovell Hall (4.3 miles south of Ascott d'Oyley) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- What level of public liability insurance do they hold?
- Their pre-qualification and accreditations
- Will failed sealant be removed rather than covered?
What affects the price in Ascott d'Oyley
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- How much existing material needs removing
- Any access equipment needed
- Backing rod, priming and other preparation
- Location, for remote and island sites
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Sending details for a quote
A good diagnosis starts with the right details. Let us know:
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
- Whether an asbestos survey exists
- Whether the building will be occupied during the work
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Common questions from Ascott d'Oyley clients
Can the mastic package for our job in Ascott d'Oyley follow the site programme?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Ascott d'Oyley too far out for you?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Who decides which product is used?
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.
What do you charge?
Each job is quoted on its own details. For yours, phone 01277 525 020 or use the quote form.
Can fire-rated sealing at service penetrations be included?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Record requirements are confirmed at quote stage.
Is the mastic package guaranteed?
Each package is signed off with a 12-month workmanship guarantee. Damage by others after we’ve finished isn’t covered.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Why deal with it now?
Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area usually clears more for less disruption, and avoids repeated visits. Snagging can be priced as a separate stage. For buildings around smaller places like Ascott d'Oyley, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
