How we handle gutter sealing in Rickmansworth
We work across Rickmansworth 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. Common call-outs are for rain getting in around a garage door and drips from gutter joints and end caps, on uPVC fascias, gutter joints and roofline trims.
Rickmansworth mixes older houses and their gutters with newer estates of brick, render and uPVC trims. All of those joints move, so they need a flexible sealant rather than a rigid filler.
Whatever the size of the job, you get the same one-year guarantee in Rickmansworth and across Hertfordshire.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
For landlords and businesses
If you manage several properties in or around Rickmansworth, several properties can go on one quote. Send us the addresses and the work at each, and pictures by email help.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
When to call us in Rickmansworth
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away over time.
The most common problems we see are:
- Old gutter sealant that has let go
- Open joints in fascias and soffits
- Internal damp traced to a gutter joint
- Water running down the wall below the gutter
If you look after a building such as Saint Joan of Arc Catholic School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Questions from Rickmansworth
What guarantee comes with gutter sealing in Rickmansworth?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can you do gutter sealing in Rickmansworth?
Yes. We work across London and the South East, and Rickmansworth is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How long before the joint can be used?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Is sealing fascia joints something you do?
Yes. Open joints along uPVC fascias and soffits can be sealed in a colour to suit.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Do you clean gutters?
We clear debris near the joints, so the sealant can bond. Cleaning the whole run is a separate job.
When it is not the sealant
To be straight with you, some problems need a different trade:
- Boards that have decayed or split
- Brackets that have snapped or loosened
- Cracked, split or warped gutter sections
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

The price is agreed before any work begins. It takes into account:
- The product the joint needs
- The size of the job
- The old material and how stubborn it is
- Working hours on commercial sites
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

What happens on the day
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins.

Why act early in Rickmansworth
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp, so it’s worth sealing early. Gaps in sealant and mould in the bead never get better on their own, and in a busy home in Rickmansworth they get worse with every use. Replacing the sealant now is the simplest fix.

Rickmansworth buildings and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Chenies Manor House (about 3.7 miles north-west) nearby, there’s older building stock in the area around Rickmansworth 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.
If you live in an older home near Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Rickmansworth station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
