Mastic sealing near North Crawley
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
How the quote is worked out
The price varies from site to site. Expect it to depend on:
- How much existing material needs removing
- Joint width, depth and condition
- Working within restricted access windows
- The site’s rules and procedures
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
However big the job, the same details help:
- How the joints are reached, and at what height
- The site address and postcode
- The type of building and who uses it
- Any dates the work must fit around
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
How we handle mastic sealing in North Crawley
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. The enquiries we see most involve movement joints with sealant missing and estate-wide sealant that is simply worn out, across balcony and threshold joints, communal entrances and stairwells and window and door perimeters on blocks. For commercial sealant work in North Crawley, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In and around smaller places like North Crawley, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

General trades versus a specialist
Redoing a failed joint normally 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.
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. A poor seal in places like these tends to cost more to put right later.

Your questions answered
Is North Crawley too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you quote for mastic across several buildings in and around North Crawley?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
How long does a typical visit take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
What happens if it’s left?
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once and is simpler to manage and budget. Halls, stores and units around places like North Crawley may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Looking after buildings in and around North Crawley
North Crawley lies roughly 47 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. The South East is one of the drier parts of the UK. 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.
If you own or manage units on a site such as Cranfield Technology Park, 2 miles south of North Crawley, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Schools and community buildings such as North Crawley CofE School need frame and external mastic kept sound like any building.

When to call us in North Crawley
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
Look out for the following:
- Communal area joints that look neglected
- Brittle perimeter mastic across a building
- Repeated reactive repairs to the same buildings
- Failed external movement joints
Trustees of buildings like Church of St Firmin can bring frame and external mastic into a planned maintenance list.
