When to call us in Sandhurst
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.
Most enquiries start with something like this:
- Repeated reactive repairs to the same buildings
- Communal area joints that look neglected
- Leaks at window and door perimeters
- Mastic failing across several blocks on an estate
Schools and community buildings such as Sandhurst School need frame and external mastic kept sound like any building.
What your quote should include
- How long is the guarantee, and what does it include?
- Will failed sealant be removed rather than covered?
- Who will actually carry out the work
- Their pre-qualification and accreditations
Mastic sealing in Sandhurst
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. If you are dealing with cracked, hardened mastic round windows on a block and leaks at window and door perimeters, we can help. Facilities teams, main contractors and managing agents in Sandhurst tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In a town such as Sandhurst, buildings managed by agents and landlords range from flats over shops to small blocks and offices. Window and door perimeters, external joints and communal areas all need their mastic renewed from time to time.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Planned mastic for Sandhurst portfolios
Sandhurst is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. At about 32 miles from central London, Sandhurst is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Property owners at sites such as The Meadows Business Park (1.2 miles south of Sandhurst) can have mastic renewed between lettings. Churches, halls and community buildings such as St George's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Sandhurst: questions and answers
Will you price a mastic programme across our Sandhurst portfolio?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
Will you take on work at estates like The Meadows Business Park, close to Sandhurst?
Yes. Our area takes in Sandhurst and its surroundings, with estates and business parks such as The Meadows Business Park included. A few photos and the unit address let us price the work.
Can you send RAMS and CSCS details before starting?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Does weather matter for sealant work?
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. Inside work is seldom held up.
Can you take on resealing for a block portfolio?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Group repairs into a planned programme
- Keep bins and bikes away from communal door frames
- Keep a record of when each building was resealed
- Check the asbestos register before any old mastic is disturbed
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.
Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.
How a job runs
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Most work in Sandhurst is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.
- We inspect the joints, building by building, and record what has failed and why.
- 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.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Point out parking and an unloading spot
- Tell us your opening times and when work is allowed
- Tell us which areas need to stay in use

Surface by surface
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.
Window and door perimeters on blocks
Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.
What happens if it’s left?
Draughts round window perimeters cost occupiers comfort and the windows typically get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. A failed joint is easier to put right before damp shows inside. After a leak, there’s drying, repairs and redecoration on top.
Pricing mastic joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.
