Mastic sealing for commercial buildings in Newell Green
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. If you have open joints in brickwork or panels and brittle perimeter mastic across a building, we can put it right, on external wall and movement joints, communal entrances and stairwells and window and door perimeters on blocks alike. Looking for mastic applicators who cover Newell Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
In and around smaller places like Newell Green, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

After the work
Keep the joints in good shape with a few simple steps:
- Include mastic in your cyclical inspections
- Have the asbestos survey to hand for older buildings
- Plan resealing building by building rather than complaint by complaint
- Make it easy for occupiers to report draughts
If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Leaks from above rather than through a joint
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Glazing that needs replacing
Not sure which it is? You can give us a call on 01277 525 020 or email us and we will tell you honestly.
Joints and surfaces we work on

Why it’s worth doing now in Newell Green
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure with less control over timing. Halls, stores and units around places like Newell Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Doing it in-house
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Newell Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

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.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
