Mastic sealing in Ashwell
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. If you are dealing with damaged joints in communal entrances and corridors and movement joints with sealant missing, we can help, on shopfronts below residential blocks, communal entrances and stairwells and external wall and movement joints alike. Searching for sealant specialists in Ashwell? We’ve been sealing commercial buildings since 2005.
In a smaller place such as Ashwell, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Quoting for work in Ashwell
We price every job individually. The main factors are:
- Working within restricted access windows
- The total length or number of joints
- Access and working height
- Distance, for remote addresses
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Asbestos survey details if the building is older
- Photos of the joints, close up and from further back
- The postcode of the building
- Access details, including height
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Questions about Ashwell
Do you take on block-wide or estate-wide mastic work in Ashwell?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we will give a fixed quote.
Is Ashwell too far out for you?
No. Places such as Ashwell are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we will tell you how we’d approach it.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
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.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Substrate edges that need repairing first
- Broken glass or failed sealed units
- Frames that are rotten, warped or broken
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
Joints and surfaces we work on

How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Work in places the size of Ashwell is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
What we need from you
- Share your working hours and any access restrictions
- Clear stock, furniture or equipment away from the joints
- Agree which areas must stay open
Getting a fixed quote
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to ring 01277 525 020 or send details through our quote form.

Common problems we fix in Ashwell
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.
Site and facilities staff are often the first to spot these:
- Repeated reactive repairs to the same buildings
- Water getting in round frames after rain
- Communal area joints that look neglected
- Failed external movement joints
Schools and community buildings such as Ashwell Primary School need frame and external mastic kept sound like any building.
What your quote should include
- Who will actually carry out the work
- Whether old or failed sealant will be cut out, not overlaid
- What site paperwork they can supply
- Can the work be phased to keep areas open?
Frames, entrances and external joints in Ashwell
The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first. Central London is about 37 miles from Ashwell. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate.
Historic properties like Hinxworth Place (1.8 miles west of Ashwell) show the age of some local stock, where frame mastic must suit soft brick or stone. Blocks of flats and mixed-use buildings often cluster around stations such as Ashwell & Morden station (2 miles east of Ashwell) and their window and balcony mastic tends to age at the same rate across a building.
Ashwell is about 5 miles north-east of Letchworth, in Hertfordshire.

When to bring in a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Why deal with it now?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and normally fails within a short time. Cutting out and resealing properly does it once. Small buildings around Ashwell suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
