Mastic sealing in Fleet
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
How the job changes by surface
Tenement and older buildings
Older mastic can contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Mastic sealing for commercial buildings in Fleet
Across Fleet and the rest of Hampshire, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote, and site visits can be arranged. The enquiries we see most involve failed external movement joints and brittle perimeter mastic across a building, on communal kitchens and washrooms, communal entrances and stairwells and balcony and threshold joints. Most enquiries from Fleet start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Older buildings in towns like Fleet have often had replacement windows fitted at different times, which leaves perimeter mastic of very different ages. Looking at the whole building first shows what needs doing now and what can wait.
Every job we finish is backed by a 12-month workmanship guarantee, in Fleet as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Questions about Fleet
Is Hart Shopping Centre, near Fleet, within your area?
Yes. Our area takes in Fleet and its surroundings, with estates and business parks such as Hart Shopping Centre included. To start, just give us a call on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Can work in a care setting near Fleet go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. We follow the home’s own procedures throughout.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Who decides which product is used?
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.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
How long does a job like this take?
It depends on the scope, but the work usually takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we will set out a timescale with the quote.
Blocks and managed buildings in Fleet
Three care or nursing homes sit less than 2 miles from Fleet. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents. At about 36 miles from central London, Fleet is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.
Owners of student blocks near University for the Creative Arts, 4.2 miles to the south of Fleet, can schedule frame and external mastic for the summer vacation. Blocks of flats and mixed-use buildings often cluster around stations such as Fleet station, 1.2 miles to the north of Fleet, and their window and balcony mastic tends to age at the same rate across a building. Site managers at schools like Heatherside Junior School can fit frame mastic into the summer works.

Advice
Building owners, agents and FMs in Fleet
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Should maintenance staff do it?
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. Getting these wrong usually costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
After the work
After handover, a little attention goes a long way:
- List the paperwork your organisation requires when you send details
- Have the asbestos survey to hand for older buildings
- Track which buildings were done and when
- Group repairs into a planned programme
If paintable sealant was used, decoration can follow once it has cured. Silicone typically can’t be painted, so keep decorators off it.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Substrate edges that need repairing first
- Leaks through the frame itself rather than the perimeter
- Water coming in from the roof or rainwater goods
If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
