Construction mastic in Bagnor
On a new build, the mastic package is one of the last trades through each area, so it lands at exactly the point the programme is tightest. Mastic Doctor takes on mastic packages for main contractors and developers. We work on cladding and panel joints, brick and block movement joints and window and door perimeters, and the usual reasons a site gets in touch are mastic snags holding up handover and sanitary sealant damaged by following trades. Most enquiries from Bagnor 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.
In the countryside around places like Bagnor, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Don’t schedule sealing before decorators and flooring are done
- Ask cleaners to use soft cloths around fresh sealant
- Don’t force external sealing on a damp or frosty day
- Check frame gaps are within the sealant’s range before sealing
A new structure shifts as it loses construction moisture. The right product in each joint copes with that while rigid fillers and caulk can crack where movement is larger. If that happens, let us know.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating, and a delay to handover. Checking perimeters before internal finishes go on avoids it.

Why deal with it now?
When a package runs over budget, downgrading the product is a common first thought. The saving is small next to the cost of callbacks and defects and external joints are where it shows first. Where an alternative is genuinely suitable, we’ll say so. For buildings around smaller places like Bagnor, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Common questions from Bagnor clients
Can work at a site such as Newbury College fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you cover business parks and estates near Bagnor, such as Parkway Shopping Centre?
Yes. Our area takes in Bagnor and its surroundings, with estates and business parks such as Parkway Shopping Centre included. Send details of the unit and the work through our quote form for a quick quote.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
What joints do you seal on a new build?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. We price to the specification and drawings.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Can you work to our specification?
The specified product is what goes in. If we think an alternative would suit better, we put it to you first.
Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Rework caused by others damaging completed areas
- Frames fitted out of tolerance
- Defective windows, doors or glazing units (the supplier or installer’s job)
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Advice
Owners, agents and contractors
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Sites and facades in and around Bagnor
Bagnor has a good number of hotels close by, all within 2 miles. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
Hotel extensions and refits, at places such as The Vineyard Hotel, which lies west of Bagnor, typically run between busy periods, so the sealing is squeezed into short windows. When units on a site such as Parkway Shopping Centre (1.2 miles east of Bagnor) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. On a healthcare site such as West Berkshire Community Hospital, which lies east of Bagnor, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
