Victoria: your questions answered
Is parking a problem for a job in Victoria?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Is Victoria in your area for gutter sealing?
Yes, Victoria is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
How long will you be here?
Typically it takes a few hours, depending on the number of joints and the access. Bigger jobs take longer.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once.
Gutter sealing in Victoria
We work across Victoria on leaking gutter joints and roofline trims. Low-level work is straightforward, and for higher work, tell us about access and we’ll confirm what’s needed. We work on gutter joints, garage door frames and gutter end caps, and common reasons people get in touch are wet patches on the wall under a gutter joint and damp on an inside wall under a dripping gutter.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.
You get a 12-month guarantee, the same in Victoria as everywhere else we work.

What we do, step by step
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take an hour or two for a few joints, longer for a full run, and we explain the cure time before we leave. In Victoria, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height

Leave it or put it right?
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp, so it’s worth sealing early. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Victoria.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Why choose Mr Mastic in Victoria
- Anti-fungal sanitary silicone in wet areas
- A 12-month guarantee on all work
- Old sealant always removed completely
- Sealant colour chosen to suit
What affects the quote in Victoria
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether the work is at height
- The type of sealant required
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
Combining jobs into one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
What to tell us for a quote
To make quoting easier, please include:
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Whether it has been sealed before
- Where the job is, and your postcode
For a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. We’ll give you a clear price before any work starts.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Have sagging gutters refixed early
- Glance at the soffit joints now and then
- Look at the gutters while it’s raining
- Clear leaves and moss from the gutters
While checking gutters, glance at the fascia joints too. A small split is quicker to put right.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry and the wall below.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Water backing up from a blocked pipe
- A gutter length that has split
- Sagging gutters or broken brackets
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
Joints and surfaces we work on
- Gutter joints
- Garage door frames
- Gutter end caps
- uPVC fascias
- Soffit joints
- Roofline trims
When to call us in Victoria
End caps get knocked or pushed by water. Once the seal behind them fails, they drip and runs down the wall.
Look out for these signs:
- Drips from gutter joints and end caps
- Old gutter sealant that has let go
- Rain getting in around a garage door
- End caps that drip every time it rains
Schools such as St Peter's Eaton Square CofE Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- How long to leave it before use
- What happens if the job turns out different
- Whether the sealant suits the joint
- What preparation is included
Victoria buildings and the weather
Historic houses like Buckingham Palace (about 0.4 miles north) are a reminder that the area around Victoria has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
As a London address, Victoria can be tricky for parking: let us know about parking bays, permits or a driveway. Homes close to St. Michael's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
