Cranbourne: questions and answers
Is Cranbourne off your patch?
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 quote for mastic across several buildings in and around Cranbourne?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
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, so we will confirm the curing time on the day.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
How long does a typical visit take?
It depends on the scope, but the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you take on resealing for a block portfolio?
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.
Mastic sealing for commercial buildings in Cranbourne
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. Resealed mastic joints in Cranbourne carry our 12-month guarantee. Most enquiries involve complaints coming in block by block and occupiers reporting cold air round windows, on balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells. For commercial sealant work in Cranbourne, you deal with one contact from quote to sign-off, whether it’s one building or several.
Rural conversions near places like Cranbourne often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Working within restricted access windows
- Whether old sealant has to be cut out first
- How much there is to seal
- The site’s rules and procedures
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Access details, including height
- The type of building and who uses it
- Whether an asbestos survey exists
- Any specification or named product
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. Rural sites near Cranbourne may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Preparing the site
- Let us know about inductions and permits
- Tell us your opening times and when work is allowed
- Tell staff and tenants when we will be in

Maintenance after handover
To get the most from the new sealant:
- Share your contractor requirements early
- Log resealing dates block by block
- Group repairs into a planned programme
- Check sealant joints during planned building inspections
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Why act early in Cranbourne
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. Converted and older buildings near places like Cranbourne tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
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.
Why us?

Looking after buildings in and around Cranbourne
Central London is about 25 miles from Cranbourne. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. Cranbourne 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.
Buildings close to stations like Ascot station, 3 miles south of Cranbourne, are often flats over shops, with frame mastic to keep sound. Older community buildings, Church of St Peter among them, often have frames of mixed ages whose mastic varies.
Cranbourne is about 3 miles south-west of Windsor, in Bracknell Forest. We cover Cranbourne, with the same fixed quotes and 12-month guarantee as everywhere else. 48 places across Bracknell Forest fall within our area, Cranbourne among them. Reading is covered too, around 13 miles from Cranbourne.

When to call us in Cranbourne
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.
What tends to prompt an enquiry:
- Complaints coming in block by block
- Mastic failing across several blocks on an estate
- Damp patches beside frames
- Draught complaints from residents or tenants
Student blocks close to universities like Imperial College Silwood Park Campus (to the south of Cranbourne) are easiest to work on between tenancies.
What to look for in a quote
- Whether old or failed sealant will be cut out, not overlaid
- What level of public liability insurance do they hold?
- Whether their applicators hold CSCS cards
- Whether primer will be used where the manufacturer specifies it
