Mastic sealing across Hundred Acres
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Asbestos-containing sealant, which we don’t remove
- Failed window or door frames, which need a window contractor
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

About our mastic sealing in Hundred Acres
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. The enquiries we see most involve draughts at frames across a block and water getting in round frames after rain, on external wall and movement joints, balcony and threshold joints and communal entrances and stairwells. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hundred Acres, preparation and product choice get the time they need.
For buildings around smaller places like Hundred Acres, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.
A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or send photos by email and we will come back to it.

Signs you need mastic sealing in Hundred Acres
UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Clients typically get in touch after noticing something like this:
- Brittle perimeter mastic across a building
- Damp patches beside frames
- Draughts at frames across a block
- Complaints coming in block by block
If you look after a block within reach of Fareham station, which lies south-west of Hundred Acres, frame and balcony mastic can be renewed on one programme.
Questions to ask before you book
- The named product and why it was chosen
- What level of public liability insurance do they hold?
- What site paperwork they can supply
- Whether old or failed sealant will be cut out, not overlaid

Mastic sealing in Hundred Acres: the local picture
Hundred Acres sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first. Hundred Acres lies roughly 62 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
If you’re responsible for a building such as Church of St Nicholas, frame and door mastic needs the same attention as any other property. Landlords with units on estates such as Knowle Village Business Park (2.5 miles south-west of Hundred Acres) can bring frame, door and external mastic across several units into one programme.

Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
Surface by surface
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. Each block is priced and scheduled in order.
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
On site: what to expect
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking a day or two for a single block, longer for an estate programme. For work around Hundred Acres, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- 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.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready

- Approximate linear metres or a joint schedule
- Clear photographs of the problem areas
- Any dates the work must fit around
- Where the site is, with the postcode
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
