What happens if it’s left?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Older rural buildings around Sarsden move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Mastic sealing in Sarsden
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints, and what we’re called in for most is the same joint failures repeated across a portfolio and occupiers reporting cold air round windows. For commercial sealant work in Sarsden, you deal with one contact from quote to sign-off, whether it’s one building or several.
For buildings around smaller places like Sarsden, we group work so one trip covers it. Send photographs of the frames and joints and we will give a fixed quote.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Building owners, agents and FMs in Sarsden
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Cost factors for mastic joints
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- The size and state of each joint
- Removal of failed or old sealant
- Which sealant the job calls for
- The site’s rules and procedures
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What we need to price the job
However big the job, these details speed things up:
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
- Any dates the work must fit around
- The postcode of the building
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Sarsden are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Move anything stored against the joints
- Send your site hours and access windows
- Send any specification or drawings in advance

Planned mastic for Sarsden portfolios
Sarsden sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first. At about 70 miles from central London, Sarsden is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
With historic buildings such as Chastleton House, 4.3 miles to the north-west of Sarsden, in the wider area, owners of older properties around Sarsden should expect mastic to need a product that suits old masonry. Churches, halls and community buildings such as Church of St James are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Landlords with units on estates such as Station Road Industrial Estate (2.3 miles north-east of Sarsden) can bring frame, door and external mastic across several units into one programme.
Sarsden is about 9 miles north-west of Witney, in Oxfordshire. We cover commercial sites throughout Sarsden, for single jobs and planned programmes alike. Sarsden is one of 423 places we cover in Oxfordshire for mastic joints. For work in that direction, see our Oxford page, about 18 miles away.

Should maintenance staff do it?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
