Mastic sealing across Mottisfont
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Looking after the joints
After handover, these steps help:
- Encourage occupiers to report problems at frames
- Mention RAMS, insurance or CSCS requirements up front
- Prioritise elevations facing the weather
- Plan resealing building by building rather than complaint by complaint
Keep records of when each building was resealed. That makes future programmes easier to plan and gives you a history.
One failed perimeter typically means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
How we handle mastic sealing in Mottisfont
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 and backing rod used wherever a joint is deep. The enquiries we see most involve old repairs sealed over failed mastic and window mastic that has split and shrunk, on communal entrances and stairwells, external wall and movement joints and communal kitchens and washrooms. Facilities teams, main contractors and managing agents in Mottisfont tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Owners and agents with buildings around smaller places such as Mottisfont tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Every job we finish is backed by a 12-month workmanship guarantee, in Mottisfont as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Why act early in Mottisfont
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. Around Mottisfont, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Substrate edges that need repairing first
- Misted or failed double-glazed units
- Materials that need asbestos testing before work
If you are not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer.

Looking after buildings in and around Mottisfont
Mottisfont is about 70 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Rainfall across the South East, Mottisfont included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
For owners of several units at places like Home Farm Business Centre, 2.2 miles to the west of Mottisfont, one programme can deal with frame and external mastic across the lot. Blocks of flats and mixed-use buildings often cluster around stations such as Mottisfont & Dunbridge station (to the south-west of Mottisfont) and their window and balcony mastic tends to age at the same rate across a building. Older buildings near Mottisfont, from historic houses such as Mottisfont Abbey, 0.2 miles to the north-east of Mottisfont, to more modest stock, need compatible products when frames are resealed.

Common questions from Mottisfont clients
Do you cover business parks and estates near Mottisfont, such as Home Farm Business Centre?
Yes. Our area takes in Mottisfont and its surroundings, with estates and business parks such as Home Farm Business Centre included. A few photos and the unit address let us price the work.
Will you take on a block within reach of Mottisfont & Dunbridge station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Does weather matter for sealant work?
Outside, 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.
