Willian: questions and answers
Can work in a care setting near Willian go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.
Is Willian 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.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
When is resealing likely to be due?
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.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
About our mastic sealing in Willian
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use throughout. If you’re dealing with a mix of products and colours from past repairs and brittle perimeter mastic across a building, we can put it right, whatever the surface. For commercial sealant work in Willian, you deal with one contact from quote to sign-off, whether it’s one building or several.
Rural conversions near places like Willian often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
A 12-month guarantee applies to all our work in Hertfordshire. Should something we installed fail, speak to us on 01277 525 020 or use the quote form and we’ll come back to it.

Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes one or more days per building, depending on the joint lengths and the access.

Advice
What sealant work can’t fix
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Leaks from above rather than through a joint
- Substrate edges that need repairing first
- Frames that are rotten, warped or broken
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
Joints and surfaces we work on
- External wall and movement joints

Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
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.
Owners, agents and contractors
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Why act early in Willian
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. Converted and older buildings near places like Willian tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Prioritise elevations facing the weather
- Protect low-level joints in entrances
- Keep a record of when each building was resealed
- Avoid piecemeal callouts where you can
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.

What else we do in Willian
For owners and agents in Willian
At about 32 miles from central London, Willian is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Willian is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
Trustees of buildings like Church of All Saints can bring frame and external mastic into a planned maintenance list. Property owners at sites such as Letchworth Gateway Retail Park (1.4 miles north-east of Willian) can have mastic renewed between lettings. If your remit includes a building such as Lordship Farm Primary School, frame and door mastic can be programmed for the holidays.
