Mastic sealing in Whitton, done properly
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. Site teams most often ask us about window mastic that has split and shrunk and draught complaints from residents or tenants, on shopfronts below residential blocks, communal entrances and stairwells and window and door perimeters on blocks. A specialist sealant contractor works differently from a general builder: on jobs in Whitton, preparation and product choice get the time they need.
For managing agents in Whitton, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

How a job runs
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. All of Greater London is in the ULEZ, and kerbside space in Whitton can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- 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.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings
- Point out any areas we must not close

FAQs: Whitton
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
We manage a building near Whitton station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so there are no surprises.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Can people stay in the building while you reseal?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
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. In Whitton, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
Why appoint us
- A Constructionline member, so easy to vet
- A range of standard colours, depending on the product
- Products installed to the manufacturer’s instructions
- RAL and finish matching where the product range allows
Take a look at what affects the cost and how we’re accredited.
Site staff or a sealant specialist?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Whitton can sit alongside others in a wider programme across Greater London.
