What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Faulty frames rather than failed sealant
- Joint design decisions that belong to the architect or engineer
- Damage to finishes by other trades after we have sealed
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly.
What we seal
- Brick and block movement joints
- Cladding and panel joints
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Window and door perimeters
- Floor and skirting junctions
Construction mastic in Wraysbury, done properly
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list, and every return visit costs time. We seal so the snag list stays short. We work on internal decorators’ caulk, brick and block movement joints and window and door perimeters, and what we’re called in for most is frame perimeters left unsealed or poorly sealed and new external sealant already peeling away. Looking for mastic applicators who cover Wraysbury? We’ve been sealing commercial buildings since 2005.
Conversions around smaller places like Wraysbury often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Different surfaces, different methods
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent.
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area and damaged joints are redone rather than patched.
Looking after the joints
Once the work is signed off, these steps help:
- Note which sealant went where at handover
- Ask for joint and product checks before the package is urgent
- Protect sealed areas from following trades
- Allow flexibility for external sealing in damp or cold weather
Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked, and that time depends on the product, temperature and joint depth.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
Cost factors for mastic packages
What shapes the price:
- Backing rod, priming and other preparation
- Which sealant the job calls for
- Whether the work must be split into stages
- How much there is to seal
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
What we need to price the job
A few photos plus some basic facts will normally do. Please tell us:
- The postcode of the building
- Drawings or a marked-up plan, if available
- Any specification or named product
- Your programme or deadline
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email a schedule or drawings to discuss it first.

Leave it or put it right?
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites rather than at the snagging stage. Leave it late and they turn up on the snag list. For buildings in places like Wraysbury, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
What you get with us
- A fixed quote before work starts
- RAL and finish matching where the product range allows
- Standard and matched colours in many product ranges
- Sealing commercial buildings since 2005
How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If neighbouring businesses or buildings around Wraysbury need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Flag any permit to work we’ll need
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
Getting a fixed quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email a schedule or drawings.

Construction mastic in Wraysbury: the local picture
Wraysbury lies roughly 20 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Wraysbury sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.
For contractors on a campus like Royal Holloway University, 2.3 miles south of Wraysbury, facade and perimeter sealing has to fit around students and term dates. For a contractor working at a hospital such as Princess Margaret Hospital (2.4 miles north-west of Wraysbury), perimeter and facade sealing is planned around patients and deliveries. Further education sites such as Strode's College, 1.8 miles south of Wraysbury, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Wraysbury is about 2 miles north of Egham, in Windsor and Maidenhead. We cover commercial sites throughout Wraysbury, whether it’s a single job or part of a planned programme. Wraysbury is one of 60 places in Windsor and Maidenhead on our list. For work in that direction, see our Reading page.

Questions about Wraysbury
Can you take on a job at a hospital such as Princess Margaret Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is a smaller place like Wraysbury outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Do you install fire-rated sealant as part of a package?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Record requirements are confirmed at quote stage.
Are you CHAS accredited?
We are CHAS accredited and a Constructionline member, and each applicator is CSCS-carded. Public liability insurance is in place.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What does a mastic package usually include?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens.
