Mastic sealing for Sheet sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
On site: what to expect
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. Jobs in and around smaller places like Sheet are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
- Tell us what induction or permit system the site runs
- Move anything stored against the joints
- Tell staff and tenants when we’ll be in

How we handle mastic sealing in Sheet
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you have patchy repairs in mismatched sealant and open joints in brickwork or panels, we can help, whatever the surface. One point of contact handles commercial sealant work in Sheet from the first photographs to the final walk-round, for single jobs and planned programmes alike.
For buildings around smaller places like Sheet, we group work so one trip covers it. Send photos of the frames and joints and we will give a fixed quote.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Masonry that has broken away beside the joint
- Failed window or door frames, which need a window contractor
- Misted or failed double-glazed units
If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think.
What we seal
- Window and door perimeters on blocks
- Balcony and threshold joints
- External wall and movement joints
- Communal kitchens and washrooms
- Communal entrances and stairwells

Your questions answered
Can you work at a site such as Upper Adhurst Industrial Park, by Sheet?
Yes. We cover Sheet and the area around it, including industrial estates, business parks and retail parks such as Upper Adhurst Industrial Park. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
Is Sheet off your patch?
No. Places such as Sheet are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How do you handle work on occupied blocks?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
For owners and agents in Sheet
At about 49 miles from central London, Sheet is within reach of the capital. 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. 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 usually need attention first.
If you look after a block within reach of Petersfield station, which lies south-west of Sheet, frame and balcony mastic can be renewed on one programme. Property owners at sites such as Upper Adhurst Industrial Park, 1 mile north-east of Sheet, can have mastic renewed between lettings. Trustees of buildings like Church of St Mary Magdalene can bring frame and external mastic into a planned maintenance list.
Sheet is about 1 mile north-east of Petersfield, in Hampshire. Any commercial site in Sheet is covered. We work across 723 places in Hampshire, from busy centres to rural villages. Portsmouth is covered too, some 16 miles away.
We cover the GU32 and GU31 postcode districts. If your site is on Mill Lane, Village Street and Farnham Road or close by, we can quote for mastic joints. Close to Sheet, our area also takes in Petersfield (1 mile south-west), Steep (1 mile north-west), Steep Marsh (1 mile north-west), Stroud (2 miles west) and Oakshott (2 miles north-west). Bigger towns within reach include Havant (11 miles south), Horndean (8 miles south-west), Alton (10 miles north), Waterlooville (10 miles south-west), Purbrook (11 miles south-west) and Bordon (7 miles north).
Local landmarks in Sheet
We work on buildings around The Queens Head pub, Churcher's College and The Petersfield School and the streets around them. For rail, the closest station is Petersfield station, roughly 1.1 miles south-west of the centre. A little further out are Petersfield Community Hospital (1.3 miles south-west) and Bear Museum (1.1 miles south-west). Green spaces nearby include Liss Riverside Railway Walk South and Wheatham Hill.
How the quote is worked out
Each job is priced on its own details. The main factors are:
- Distance, for remote addresses
- Backing rod, priming and other preparation
- How much existing material needs removing
- Specialist products, such as fire-rated or hygienic sealants
Pricing mastic joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.
Before you send an enquiry
However big the job, the same details help:
- Anything awkward about access or site hours
- Asbestos survey details if the building is older
- Whether the building will be occupied during the work
- Rough lengths or quantities, or drawings if you have them
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Different surfaces, different methods
Planned maintenance
We can work into your cyclical maintenance plan on a timetable you set.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Owners, agents and contractors
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
