How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- The total length or number of joints
- Any access equipment needed
- Backing rod, priming and other preparation
- Travel to remote or island sites
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:
- The asbestos register, for older buildings
- Photos of the joints, close up and from further back
- What the building is and how it’s used
- Your programme or deadline
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Facade sealing in Fair Oak
External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. The enquiries we see most involve new sealant peeling off old mastic and failed sealant on precast panel joints, across coping and flashing joints, window and door perimeters and perimeter joints where frames meet the structure. Looking for mastic applicators who cover Fair Oak? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Construction in and around smaller places such as Fair Oak is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Note when each elevation was last resealed
- Check the asbestos register before old mastic is disturbed
- Keep sills, gutters and drainage paths clear
- Add perimeter sealant to planned maintenance checks
Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.
Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in instead of after the damage.
Signs you need facade sealing in Fair Oak
Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.
Common reasons buildings call us in:
- Old perimeter mastic that has dried out
- Cladding panel joints that have opened up
- Facade joints cracked through the middle
- Air leaks through failed facade joints
School extensions, at buildings such as Ashford Hill Primary School, typically run to the summer holidays, mastic included.
What your quote should include
- Who will actually carry out the work
- Can the work be phased to keep areas open?
- Will RAMS and insurance details be available?
- What the guarantee covers, and for how long
What happens if it’s left?
Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Around Fair Oak, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Common questions from Fair Oak clients
Is Scion Business Park, near Fair Oak, within your area?
Yes, sites like Scion Business Park are within our area, along with the rest of Fair Oak. Photos and a short description are enough for a first look.
Is a smaller place like Fair Oak outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
Can you look at water coming in around a frame?
Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all.
New build and refits around Fair Oak
Fair Oak is about 49 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. Fair Oak sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.
When units on a site such as Scion Business Park, 1.5 miles north-east of Fair Oak, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. New wings at hospitals like West Berkshire Community Hospital (5.5 miles north-west of Fair Oak) bring long runs of window and panel joints to seal.
