Why act early in Faringdon
A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to, and the defect comes back after handover. We cut out and redo the joint properly. In a smaller place such as Faringdon, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Why us?
- Sealing commercial buildings since 2005
- One phone line for London, the South East and Scotland
- RAL and finish matching where the product range allows
- Products installed to the manufacturer’s instructions

Construction mastic for commercial buildings in Faringdon
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. We work on cladding and panel joints, sanitary and kitchen joints and brick and block movement joints, and the usual reasons a site gets in touch are external joints sealed in damp or cold conditions that are now failing and different trades sealing to different standards. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Faringdon, preparation and product choice get the time they need.
Around places like Faringdon, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Signs you need construction mastic in Faringdon
On construction sites, joints typically fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, so they end up back on the snag list.
Things that typically lead to an enquiry:
- Bath and shower joints scraped during the final clean
- Mastic snags holding up handover
- New external sealant already peeling away
- Cracks opening in caulked internal joints
Hotel extensions and refits, at places such as The Crown Hotel, which lies north of Faringdon, usually run between busy periods, so the sealing is squeezed into short windows.
What to look for in a quote
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- The named product and why it was chosen
- Whether primer will be used where the manufacturer specifies it
- Are they CHAS accredited or on Constructionline?

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
Building owners, agents and FMs in Faringdon
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Common questions from Faringdon clients
Is a hospital such as Faringdon Day Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Is Faringdon too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we will price the work to it.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
What do you charge?
Each job is quoted on its own details. For yours, call the office on 01277 525 020 or send photos by email.
After the work
For the best life from the joints:
- Brief the final clean team to avoid blades near sealant
- Stick to the specified sealant rather than a generic substitute
- Brief following trades on areas that have been sealed
- Allow flexibility for external sealing in damp or cold weather
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out and keeps handover on track.
Sites and facades in and around Faringdon
Faringdon is about 65 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. There are a number of hotels within about 2 miles of Faringdon. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
For contractors refurbishing units at places like Faringdon Business Park, which lies south-west of Faringdon, the mastic covers cladding panels, roller-door and window perimeters. Hospital estates such as Faringdon Day Hospital, less than half a mile to the north of Faringdon, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
