Mastic sealing for commercial buildings in Shepperton
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. Site teams most often ask us about the same joint failures repeated across a portfolio and leaks at window and door perimeters, on shopfronts below residential blocks, window and door perimeters on blocks and external wall and movement joints. Searching for sealant specialists in Shepperton? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Older buildings and conversions around places like Shepperton mix old masonry with newer frames. The mastic there needs to suit both surfaces.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Site staff or a sealant specialist?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Putting right a botched joint often costs more than sealing it well at the start, 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.
What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Water coming in from the roof or rainwater goods
- Failed window or door frames, which need a window contractor
- Substrate edges that need repairing first
If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
Joints and surfaces we work on

For owners and agents in Shepperton
Shepperton has two care or nursing homes no more than 2 miles away. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. Central London is about 17 miles from Shepperton. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.
Schools and community buildings such as Thamesmead School need frame and external mastic kept sound like any building. Property owners at sites such as Shepperton Business Park (less than half a mile north of Shepperton) can have mastic renewed between lettings. With historic buildings such as The Homewood (to the south-east of Shepperton) in the wider area, owners of older properties around Shepperton should expect mastic to need a product that suits old masonry.

What happens if it’s left?
Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure and less choice about when. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Your questions answered
Does your area include sites such as Shepperton Business Park, near Shepperton?
Yes. Estates, retail parks and business parks around Shepperton, Shepperton Business Park among them, are all within reach. A few photographs and the unit address let us price the work.
Can you quote for a block close to Shepperton station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Do you work with property factors and landlords?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Share the asbestos register when you send details
- Track which buildings were done and when
- Make it easy for occupiers to report draughts
- Make mastic part of routine maintenance checks
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
