- When we can work, for business premises
- Whether old sealant or filler has to be cut out

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:

Every job is quoted individually. Just ring 0345 464 0079 or drop us an email with the details and send photos if you have them.
When it is not the sealant
A few problems are outside what sealant work can do:

FAQs for De Beauvoir Town
Can parking be tricky for a visit in De Beauvoir Town?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
I let a flat near Dalston Junction station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Can a leaking gutter joint be sealed?
Most of the time. A sagging or cracked gutter needs more than sealant and we will say so.
Where is Mr Mastic based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do you work in De Beauvoir Town?
Yes. We work in De Beauvoir Town, as part of our work across South East England, London and Scotland. To book, phone 0345 464 0079 or drop us an email.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
De Beauvoir Town buildings and the weather
In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Peter, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Our Lady and St Joseph Catholic Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Why act early in De Beauvoir Town
A dripping gutter joint keeps wetting the same patch of wall. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. In a flat in De Beauvoir Town, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.
Why us?
- We never seal over old sealant
- Domestic, commercial and hotel work
- Every job guaranteed for a year
- Arbo and Everbuild products

Garage door frames
Failed sealant around a garage door frame lets water in. It’s removed and renewed.
Soffit joints
Gaps at soffit joints can let in draughts and insects. We close them with a suitable sealant.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
