How we handle mastic sealing in Shalden
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. The enquiries we see most involve window mastic that has split and shrunk and occupiers reporting cold air round windows, on external wall and movement joints, communal entrances and stairwells and communal kitchens and washrooms. Most enquiries from Shalden start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For buildings around smaller places like Shalden, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Block-wide mastic in Shalden
Shalden sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 45 miles from central London, Shalden is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations.
Trustees of buildings like Church of St Peter and St Paul can bring frame and external mastic into a planned maintenance list. If you own or manage units on a site such as Kerridge Industrial Estate, 2.1 miles south-east of Shalden, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Common questions from Shalden clients
We manage a building near Alton station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
Can you work at a site such as Kerridge Industrial Estate, by Shalden?
Yes. We cover Shalden and the area around it, including industrial estates, business parks and retail parks such as Kerridge Industrial Estate. Photos and a short description are enough for a first look.
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 does a job like this take?
That varies with the scale of the job, but the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
Do you work in Shalden?
Yes. Sites across Shalden are covered.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
What we are called out for in Shalden
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone and the repair soon fails.
It’s worth sending us details if you spot any of the following:
- Damp patches beside frames
- The same joint failures repeated across a portfolio
- Movement joints with sealant missing
- Worn sealant at communal door frames
Buildings close to stations like Alton station (2.1 miles south-east of Shalden) are often flats over shops, with frame mastic to keep sound.

- Backing rod, priming and other preparation
- Induction, permit and paperwork requirements
- Any access equipment needed
- Removal of failed or old sealant
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

How the job changes by surface
Window and door perimeters on blocks
Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. We will confirm the colours available for the specified product.
External movement joints
The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.
Building owners, agents and FMs in Shalden
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Why act early in Shalden
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. Older rural buildings around Shalden move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
