Your questions about gutter sealing in Rock
What guarantee comes with gutter sealing in Rock?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Rock within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long will you be here?
As a guide, most jobs take an hour or two for a few joints, longer for a full run. Bigger jobs take longer.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Will you clear out my gutters?
We clear debris near the joints, so the sealant can bond. A full gutter clean is a separate job.
Are you fully insured?
Yes. Full insurance covers our work.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Gutter sealing for homes and businesses in Rock
It’s easy to live with a dripping gutter joint, but each shower sends water to the same place. Resealing it is a small job if the gutter is otherwise in good order. If you have dripping gutter ends and trim joints where the sealant has failed, we can put it right, whatever the surface.
In a village or hamlet like Rock, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What else we do in Rock
Why act early in Rock
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. Older cottages and farmhouses around Rock can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes anything from an hour or two to a few hours. Somewhere like Rock needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we trace the drip and check the gutter isn’t damaged.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
Advice
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We cut it out and start again.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
If you manage several properties in or around Rock, several properties can go on one quote. Send us the addresses and the work at each.
What the job involves on each surface
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a small job to fix.
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
How we quote for gutter sealing
Call for a quick quote. What matters most is:

Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

Outside joints around Rock
With historic houses such as Parham House (about 3.9 miles west) nearby, there’s older building stock in the area around Rock 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. 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.
For site and facilities teams at buildings such as St Mary's CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around The Parish Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.
