Gutter sealing for homes and businesses in Richmond
Gutter and fascia replacement is not our trade, and nor is roofing. What sealant does is close joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. We work on roofline trims, garage door frames and uPVC fascias, and common reasons people get in touch are drips from gutter joints and end caps and streaks down the brickwork from a leaking joint.
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, and both kinds of building are found across London.
Our work is backed for twelve months, in Richmond and everywhere else we cover.

How the job changes by surface
Gutter joints
A dripping joint does not always mean a failed gutter. Sealing the joint often stops it.
Soffit joints
Soffit board joints can separate over time. We seal them to close the gaps.
What gutter sealing looks like in Richmond
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking.
Richmond is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as The Vineyard School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around The Vineyard Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Richmond is about 5 miles south-west of Kensington, in Greater London. Richmond gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. 764 places in Greater London are on our list. We also work in London, around 9 miles away.

Common questions in Richmond
Can you help a landlord with a rental near Richmond station?
Yes. We work for letting agents and landlords as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Is Richmond in your area for gutter sealing?
Yes. We work across London and the South East, and Richmond is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Do you install new fascias or gutters?
No. We seal joints and replacement is a job for an installer.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How the visit works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on the number of joints and the access. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at where the water is coming from and check the gutter is not broken or sagging.
- We clean out the joint and take out the old sealant.
- The area is dried so the sealant can bond.
- Gutter or exterior sealant is applied and finished.
- We look along the gutter and clear debris around the joints.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

How we quote for gutter sealing
You will get a clear quote before we start. It takes into account:
- How many rooms, windows or areas are involved
- Whether the work is at height
- The product the joint needs
- Working hours on commercial sites
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we will talk you through it.
What to tell us for a quote
To make quoting easier, let us know:
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- The type of property
- Access, such as stairs, a lift or height
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or drop us an email.
When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- Gutters that have dropped or pulled away
- Leaks from the roof rather than a joint
- Downpipes that are blocked or broken
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.
Where we work in Richmond

Why it’s worth doing now in Richmond
Sealant won’t clear a blocked downpipe. We check the cause first and point you to the right trade if needed. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Richmond, the repair is bigger than a sealant job.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Watch for drips in a downpour
- Don’t lean ladders against the gutter itself
- Deal with a drip before winter
- Keep downpipes clear
Look at fascia and trim joints when you’re checking the gutters. A small split is quicker to put right.
The sooner a gutter leak is sealed, the less water reaches the wall. We’ll let you know if the gutter needs more than sealant.
