Mastic sealing for Alscot sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Common problems we fix in Alscot
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
If one of these sounds familiar, it’s time for a closer look:
- Complaints coming in block by block
- Patchy repairs in mismatched sealant
- Communal area joints that look neglected
- Open joints in brickwork or panels
Trustees of buildings like St Teresa's Church can bring frame and external mastic into a planned maintenance list.
Questions to ask before you book
- Whether primer will be used where the manufacturer specifies it
- Will failed sealant be removed rather than covered?
- How they’ll work around occupants
- Are they CHAS accredited or on Constructionline?
Mastic sealing in Alscot, done properly
For blocks and buildings in Alscot and across Buckinghamshire, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. We work on window and door perimeters on blocks, communal entrances and stairwells and shopfronts below residential blocks, and what we are called in for most is no planned programme for sealant and old repairs sealed over failed mastic. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Alscot is the same: the right product in a properly prepared joint.
Rural conversions near places like Alscot often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Looking after buildings in and around Alscot
At about 36 miles from central London, Alscot is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Alscot is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
Schools and community buildings such as Princes Risborough Primary School need frame and external mastic kept sound like any building. For agents with blocks near Monks Risborough station, 0.5 miles to the north-east of Alscot, a block-wide mastic programme deals with frames, balconies and entrances in one go.
Alscot is about 6 miles east of Thame, in Buckinghamshire. Anywhere in HP27, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Buckinghamshire coverage takes in 308 places, from busy centres to rural villages. Oxford is covered too, some 17 miles away.

Cost factors for mastic joints
Your fixed quote is built from the real scope. It allows for:
- Access and working height
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
- Phasing around occupants
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.
Sending details for a quote
Good information means a firmer quote. Helpful details to send:
- Whether an asbestos survey exists
- The type of building and who uses it
- Drawings or a marked-up plan, if available
- Specification clauses that apply
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Building owners, agents and FMs in Alscot
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Alscot can form part of a wider programme.
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Encourage occupiers to report problems at frames
- Start inspections with the most exposed faces
- Keep a record of when each building was resealed
- Have the asbestos survey to hand for older buildings
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.

What else we do in Alscot
How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself typically taking anything from a day to a few weeks, depending on the number of buildings and joints. Jobs in and around smaller places like Alscot are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
Before we start on site
- Agree which areas must stay open
- Move anything stored against the joints
- Tell us your opening times and when work is allowed
Ask for a quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or send photos by email.
Advice
Why deal with it now?
Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Older rural buildings around Alscot move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
A quote for mastic joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

Your questions answered
Is Alscot too small for you to travel to?
Not at all. Alscot is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you quote for mastic across several buildings in and around Alscot?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photos and we’ll give a fixed quote.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Can people stay in the building while you reseal?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How long does a typical visit take?
It depends on the scope, but the work normally takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
