Common questions from Wintershill clients
Do you cover business parks and estates near Wintershill, such as Deer Park Farm Industrial Estate?
Yes, sites like Deer Park Farm Industrial Estate are within our area, along with the rest of Wintershill. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is a smaller place like Wintershill outside your area?
No. Places such as Wintershill are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you take on resealing for a block portfolio?
We do. 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.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How we handle mastic sealing in Wintershill
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. Site teams most often ask us about failed external movement joints and worn sealant at communal door frames, on window and door perimeters on blocks, external wall and movement joints and balcony and threshold joints. Searching for sealant specialists in Wintershill? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Owners and agents with buildings around smaller places such as Wintershill tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Check the asbestos register before any old mastic is disturbed
- Check sealant joints during planned building inspections
- Look at the sunniest and most exposed elevations first
- Keep bins and bikes away from communal door frames
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
Leave it or put it right?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Converted and older buildings near places like Wintershill tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
There’s no price list, since every building and every scope is different. Call for a quote.

Planned mastic for Wintershill portfolios
Rainfall across the South East, Wintershill included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. At about 62 miles from central London, Wintershill is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations.
