Gutter sealing in Grove Park, done properly
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter is broken or sagging, we will tell you. We are often asked to deal with rain getting in around a garage door and water running down the wall below the gutter, across uPVC fascias, garage door frames and roofline trims.
Modern London flats rely on sealed movement joints and cladding joints. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.
All our work is covered by a one-year guarantee, wherever you are in Greater London.

FAQs for Grove Park
Do you work for landlords with property near Grove Park station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Is Grove Park in your area for gutter sealing?
Yes. We work across London and the South East, and Grove Park is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Do you work on high-level gutters?
Single-storey and low-level gutters are straightforward. If it’s higher up, let us know and we’ll confirm the access.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Is there any odour?
Possibly a little. It fades as the sealant cures.
Can sealant stop a sagging gutter leaking?
Sealant won’t hold a sagging gutter. The gutter needs refixing by a gutter installer, and we’ll tell you if that is what we find.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you guarantee gutter sealing?
Our 12-month guarantee applies on every job.
What affects the cost of gutter sealing
For a quick quote, just ask. The main things that affect it are:
- The amount of work
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Doing several joints on one visit is generally more efficient than separate visits. We’ll send you a clear quote for the lot.

When you call or email, it’s useful to know:
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property

Common problems we fix in Grove Park
Sealant laid on a wet or dirty joint fails early. Rushed repairs often don’t last long for this reason.
The problems people normally mention when they call are:
- Internal damp traced to a gutter joint
- Cracked sealant along roofline trims
- Garage door frames letting rain in
- Dripping gutter ends
As a London address, Grove Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before you book
- What the cure time is
- Who turns up on the day
- What guarantee comes with the work
- Are they insured?
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Have sagging gutters refixed early
- Look at the gutters while it’s raining
- Check that water runs out of the downpipes
- Check fascia and soffit joints for gaps
Look at fascia and trim joints when you are checking the gutters. Splits are easier to seal early.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches.
Landlord and commercial work in Grove Park

If you manage several properties in or around Grove Park, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes an hour or two for a few joints, longer for a full run. In a London area like Grove Park, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.
Before we arrive
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on

Leave it or put it right?
You don’t need to replace a garage door because rain gets in round the frame. Resealing the frame joint is often enough, if the frame itself is sound. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Grove Park, the repair is bigger than a sealant job.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

What gutter sealing looks like in Grove Park
London and the South East are among the drier parts of the UK, 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 it’s worth agreeing who is responsible before work starts.
Homes close to St Augustine's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Haberdashers' Aske's Knights Academy, larger buildings have long runs of movement joint that eventually need resealing.
