How we handle mastic sealing in Aldworth
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. We work on shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints, and what we are called in for most is brittle perimeter mastic across a building and leaks at window and door perimeters. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Aldworth is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For owners with a single building near Aldworth, we plan to finish in one visit where possible. Send photographs of the frames and joints and we’ll give a fixed quote.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Common problems we fix in Aldworth
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone and the repair soon fails.
These are often picked up first by site or facilities staff:
- Repeated reactive repairs to the same buildings
- Patchy repairs in mismatched sealant
- Window mastic that has split and shrunk
- Worn sealant at communal door frames
Buildings close to stations like Goring & Streatley station, 3 miles east of Aldworth, are often flats over shops, with frame mastic to keep sound.
Questions to ask before you book
- How joint depth will be controlled
- How they’ll work around occupants
- Who will actually carry out the work
- Health and safety accreditation such as CHAS
Mastic sealing around Aldworth: points for this area
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Central London is about 48 miles from Aldworth. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Historic properties like Basildon Park, 3.6 miles to the east of Aldworth, show the age of some local stock, where frame mastic must suit soft brick or stone. Site managers at schools like The Downs School can fit frame mastic into the summer works.

What sets the cost
A fixed quote reflects the actual work. It allows for:
- Whether old sealant has to be cut out first
- Location, for remote and island sites
- Any access equipment needed
- Induction, permit and paperwork requirements
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
Details that help us quote
We can often quote from photographs and a few details. It helps to include:
- Whether the building will be occupied during the work
- Rough lengths or quantities, or drawings if you have them
- Where the site is, with the postcode
- Any specification or named product
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

How the job changes by surface
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Aldworth: questions and answers
Will you price a mastic programme across our Aldworth portfolio?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Can you quote for a block close to Goring & Streatley station?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Our process
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Aldworth can be grouped with others nearby.
