Gutter sealing in New Charlton: local notes
With historic houses such as Queen's House (about 1.8 miles west) nearby, there’s older building stock in the area around New Charlton as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.
Rented homes near Charlton station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. If you look after a building such as Royal Greenwich Trust School, its movement joints, gutters and trims need looking after like any other building’s.

Gutter sealing in New Charlton
Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where one is available. If you are dealing with old gutter sealant that has let go and gaps along fascia and soffit joints, we can help, on soffit joints, uPVC fascias and garage door frames alike.

New Charlton questions
I let a flat near Charlton station. Can you help?
Yes. We work for landlords and agents as well as householders. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Is parking a problem for a job in New Charlton?
Parking in New Charlton, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
How long does gutter sealing take?
That depends on how much there is to do, but as a guide it takes anything from an hour or two to a few hours. We will tell you when we quote.
Will sealant fix a dripping gutter joint?
Normally, if the gutter is sound. We clean and dry the joint before sealing so the seal holds.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Do you install new fascias or gutters?
No, we reseal joints and trims. A gutter installer or roofer deals with replacement.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
How we quote for gutter sealing
Your quote is based on your job. We look at:
- Mould in or behind the old joints
- How easy the joints are to reach
- The product the joint needs
- How much there is to do
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’ll go through it with you.
What to tell us for a quote
When you contact us, these details help:
- The rough size of the job
- Whether it’s a home or a business
- Any previous sealing or DIY work
- What’s wrong with the joints now
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
What we can’t put right
A few problems are outside what sealant work can do:
- Cracked, split or warped gutter sections
- Rotten or damaged fascia boards
- Problems with the roof covering
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Roofline trims

- Soffit joints

Do you need gutter sealing in New Charlton?
Leaves and moss hold water in the gutter. Standing water finds the weakest joint and drips through.
Keep an eye out for these signs:
- Open joints in fascias and soffits
- Rain getting in around a garage door
- Old gutter sealant that has let go
- Old sealant on roofline trims that has split
As a London address, New Charlton can be tricky for parking: let us know about parking bays, permits or a driveway.
Questions to ask before you book
- Whether they seal over old material or remove it
- The length of the guarantee
- How hidden problems are handled
- Which colour the sealant will be
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What the job involves on each surface
uPVC fascias
We seal fascia joints, not replace the boards. If boards are damaged, we will tell you.
Roofline trims
We seal the trims, not the roof. A roofer deals with the roof itself.

What else we do in New Charlton
Why deal with it now?
You do not need to replace a garage door because rain gets in round the frame. Sealing the frame normally stops it. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in New Charlton, the repair is bigger than the sealant job would have been.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
