Advice
How we handle gutter sealing in Selsdon
Gutter and fascia replacement isn’t our trade, and nor is roofing. Sealant fixes joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. If you’re dealing with rain getting in around a garage door and fascia boards with gaps between them, we can help, whatever the surface. We are sealant specialists rather than general builders, so gutter sealing in Selsdon is done by someone who does this every day.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so one failed joint can cause damp for more than one household. For a flat in Selsdon, check the lease for who looks after the outside.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Walls and rooflines in Selsdon
Historic houses like Addington Palace (about 1 mile north-east) are a reminder that the area around Selsdon has older buildings as well as new. 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.
If you live in an older home near St Francis, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as Selsdon Primary and Nursery School, larger buildings have long runs of movement joint that eventually need resealing.

Do you need gutter sealing in Selsdon?
Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up so we check the cause first.
Keep an eye out for these signs:
- Rain getting in around a garage door
- Cracked sealant along roofline trims
- Water dripping where gutter sections meet
- Damp patches inside below a leaking gutter
Selsdon is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before you book
- How the colour is chosen
- What guarantee comes with the work
- Are they insured?

Aftercare tips
To keep the joints looking good and working properly:
- Keep downpipes clear
- Clear leaves and moss from the gutters
- Do not lean ladders against the gutter itself
- Check fascia and soffit joints for gaps
Clear the gutters once or twice a year so water does not sit on the joints. Water left in a gutter tests every joint.
A leaking garage frame lets water reach stored items. Resealing the frame is a quick job while the frame is sound.
Your questions about gutter sealing in Selsdon
Is parking a problem for a job in Selsdon?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
I let a flat near Sanderstead station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just phone 07833 053749 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Will sealant fix a dripping gutter joint?
Often, yes. A clean, dry joint resealed with gutter sealant usually stops the drip. A split or warped section needs replacing.
Do you clean gutters?
We clear debris near the joints, so the sealant can bond. A full gutter clean is a separate job.
Do you guarantee gutter sealing?
You get our 12-month guarantee to all our work.
Do you install new fascias or gutters?
Replacement is not our trade. If a gutter is broken or sagging, we will tell you so you can call the right trade.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
What affects the quote in Selsdon
We quote each job individually. These are the things that affect it:
- The old material and how stubborn it is
- The amount of work
- The product the joint needs
- When we can work, for business premises
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- A few photos by email, if you can
- Where the job is, and your postcode
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, call 07833 053749 or email us.
Why act early in Selsdon
Replacing fascias because of open joints is usually unnecessary. A neat seal closes the gaps as long as the boards are in good condition. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why Selsdon clients choose us
- Approved under the ARBOMaster scheme
- Colour picked to suit the job
- You choose the colour before work begins

Should I try it myself first?
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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
