Different surfaces, different methods

Planned resealing replaces emergency callouts and keeps budgets predictable.
Window and door perimeters on blocks
Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.
Nashes Green: questions and answers
We manage a building near Alton station. Can you help?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is Nashes Green too small for you to travel to?
Not at all. Nashes Green is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we will tell you how we’d approach it.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Can you take on resealing for a block portfolio?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can you plan resealing across several buildings?
We can. We survey and price each building, then work through them in order starting wherever is most urgent.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Rural sites near Nashes Green may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

Advice
Planned mastic for Nashes Green portfolios
Nashes Green is about 46 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.
With historic buildings such as Hall Place, 3.3 miles south of Nashes Green, in the wider area, owners of older properties around Nashes Green should expect mastic to need a product that suits old masonry. If you look after a block within reach of Alton station, which lies south-east of Nashes Green, frame and balcony mastic can be renewed on one programme.

What else we do in Nashes Green
Common problems we fix in Nashes Green
Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.
Things that typically lead to an enquiry:
- Old repairs sealed over failed mastic
- Complaints coming in block by block
- Brittle perimeter mastic across a building
- Open joints in brickwork or panels
Churches, halls and community buildings such as Church of St. Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Quoting for work in Nashes Green
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Distance, for remote addresses
- The total length or number of joints
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- Anything awkward about access or site hours
- The type of building and who uses it
- Clear photos of the problem areas
- Where the site is, with the postcode
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Why it’s worth doing now in Nashes Green
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 Nashes Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
