Mastic sealing in Uppend
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Looking after the joints
A few simple habits keep the new joints working:
- Look at the sunniest and most exposed elevations first
- Group repairs into a planned programme
- Make it easy for occupiers to report draughts
- Reduce knocks to communal area joints
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
How we handle mastic sealing in Uppend
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you are dealing with complaints coming in block by block and cracked, hardened mastic round windows on a block, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Uppend it comes down to the same thing: the right product in a properly prepared joint.
Rural conversions near places like Uppend 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.
Our workmanship is guaranteed for 12 months, in Uppend as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Uppend: questions and answers
Is Uppend too small for you to travel to?
Not at all. Uppend 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 will plan the job to need as few trips as possible.
Does your area include sites such as Oaks Industrial Park, near Uppend?
Yes. Our area takes in Uppend and its surroundings, with estates and business parks such as Oaks Industrial Park included. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so it can be arranged.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Looking after buildings in and around Uppend
Uppend is about 30 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. Uppend 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 south- and west-facing elevations, which take the most sun and rain, often age first.
Historic properties like Much Hadham Palace (to the south-west of Uppend) show the age of some local stock, where frame mastic must suit soft brick or stone. Churches, halls and community buildings such as Church of St Mary the Virgin are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If you look after a block within reach of Stansted Mountfitchet station (2.9 miles east of Uppend), frame and balcony mastic can be renewed on one programme.
Uppend is about 3 miles north of Bishop's Stortford, in Essex. Across the CM23 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 644 places in Essex, large and small. There’s a separate page for London, roughly 30 miles from Uppend.
Anyone looking for mastic sealing in CM23 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Why it’s worth doing now in Uppend
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. One visit to deal with every failing joint makes more sense than several trips to a place like Uppend, rather than one at a time. Photos of every joint help us quote for the whole job.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Broken glass or failed sealed units
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Leaks through the frame itself rather than the perimeter
If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
