Questions from Petersham
Is parking a problem for a job in Petersham?
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.
Can you do gutter sealing in Petersham?
Yes, Petersham is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
How long will you be here?
It depends on the size of the job, but most jobs take anything from an hour or two to a few hours. We will give you a better idea when we quote.
Will sealing fix a sagging gutter?
Not on its own. A sagging gutter pulls its joints apart so it needs refixing before sealing.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages.
Do you offer different sealant colours?
Normally, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.
What do you need from me for a quote?
A short description and the location. We will ask anything else we need to know.
About our gutter sealing in Petersham
We work across Petersham on leaking gutter joints and roofline trims. Single-storey and low gutters are simple to reach and if it’s higher up, let us know and we’ll confirm what access is needed. We’re often asked to deal with cracked sealant along roofline trims and damp on an inside wall under a dripping gutter, on soffit joints, roofline trims and gutter end caps.
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.
Big or small, it’s backed by our 12-month guarantee.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Walls and rooflines in Petersham
Historic houses like Pembroke Lodge (about 0.5 miles south-east) are a reminder that the area around Petersham has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.
For an older house near a landmark such as St Peter's Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Petersham is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours, depending on the number of joints and the access. In Petersham, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- The joints are dried.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

What affects the quote in Petersham
Every job gets its own quote. These are the things that affect it:
- Whether the work is at height
- Working hours on commercial sites
- The size of the job
- The type of sealant required
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Roughly how big the job is
- How we’d reach the joints
- Whether it’s a home or a business
- Any previous sealing or DIY work
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 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.
Soffit joints
Gaps at soffit joints can let in draughts and insects. A neat seal closes them.
What we’re called out for in Petersham
Roofline sealant ages in sun and rain. It hardens, shrinks and splits after some years.
Any of these means the joints need attention:
- Wet patches on the wall under a gutter joint
- Earlier gutter repairs that have peeled off
- Stop ends leaking at the end of a run
- Trim joints where the sealant has failed
Rented homes near St Margarets (London) station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.
What to look for in a quote
- Whether the sealant suits the joint
- How long the guarantee is
- Whether they seal over old material or remove it
- Whether VAT is included

Why deal with it now?
Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right before the damage spreads. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- We never seal over old sealant
- ARBOMaster approved applicator
- We leave the area clean and tidy
- Sealant colour chosen to suit

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Check the gutters during heavy rain
- Look for streaks or damp on the wall below gutters
- Get a dropping gutter looked at quickly
- Keep downpipes clear
While checking gutters, glance at the fascia joints too. A small split is quicker to put right.
Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry.
