Common problems we fix in Farmoor
Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Most enquiries start with one or more of the following:
- Cracks opening in caulked internal joints
- Sanitary sealant damaged by following trades
- Old sealant on a refurbishment that needs stripping before new work
- Frame gaps too wide for sealant alone
Building work at universities like Azad University in Oxford (to the north-west of Farmoor) is often timed for the summer, mastic included.
What your quote should include
- How they’ll work around occupants
- Are they CHAS accredited or on Constructionline?
- What level of public liability insurance do they hold?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
How we handle construction mastic in Farmoor
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work, so we plan elevations with the forecast and the programme in mind. Internal sealing often fills those days. If you have existing joints on a refurb that need cutting out and resealing and bath and shower joints scraped during the final clean, we can put it right, on cladding and panel joints, internal decorators’ caulk and floor and skirting junctions alike. Searching for sealant specialists in Farmoor? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Sites around smaller places like Farmoor 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 photographs and the programme and we’ll quote to suit.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Frames fitted out of tolerance
- Specifying the product where the designer hasn’t
- Defective windows, doors or glazing units (the supplier or installer’s job)
If you’re not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer.
Joints and surfaces we work on
- Internal decorators’ caulk
- Cladding and panel joints
- Floor and skirting junctions
- Window and door perimeters
- Sanitary and kitchen joints
- Brick and block movement joints
General trades versus a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Work for main contractors and building owners
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Farmoor. One quote can cover more than one site, so there’s one set of paperwork to deal with.
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.
Building and refurbishing in Farmoor
At about 57 miles from central London, Farmoor is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Rainfall across the South East, Farmoor included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
On a healthcare site such as Radcliffe Infirmary, 3.7 miles to the east of Farmoor, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. When units on a site such as Oakfields Industrial Estate (1.6 miles north-west of Farmoor) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Farmoor is about 5 miles west of Oxford, in Oxfordshire. Commercial clients in Farmoor can call on us for mastic packages. Farmoor is one of 423 places in Oxfordshire on our list for mastic packages.

On site: what to expect
We begin with a short walk round with whoever looks after the building, 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. For work around Farmoor, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised straight away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Let us know about inductions and permits
- Arrange parking or a loading space

Questions about Farmoor
Can you take on a job at a hospital such as Radcliffe Infirmary?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Farmoor too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What joints do you seal on a new build?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. We price to the specification and drawings.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can staff carry on working while you’re here?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
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.
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Keep scrapers and abrasive pads off new beads
- Use the product the specification names
- Share drawings and the specification as soon as possible
- Flag uneven or tapered frame gaps early
If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors. Proper preparation, with the right silicone first time, keeps it off the defects list.
