Why act early in Bromley
A bead squeezed onto a wet joint might hold for a while but it tends to peel off. Cleaning out and drying the joint first is what makes it last. Around Bromley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

Gutter sealing in Bromley
Water dripping from a gutter joint can stain walls and soak the ground below. Often a reseal is enough, as long as the gutter is sound. Common call-outs are for water running down the wall below the gutter and rain getting in around a garage door, across gutter end caps, soffit joints and roofline trims.
Somewhere as small as Bromley, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How we quote for gutter sealing
Your quote is based on your job. We take into account:
- When we can work, for business premises
- The type of sealant required
- The amount of work
- How much old sealant there is and how hard it is to remove
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

There’s no need for technical detail. It helps if you can tell us:
- The type of property
- The rough size of the job
- Whether it has been sealed before
- Access, such as stairs, a lift or height
If you’re in Bromley and need gutter sealing, call 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you’ll get a clear quote before we start.
How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on the number of joints and the access. Somewhere like Bromley needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at where the water is coming from and check the gutter isn’t broken or sagging.
- The joint or trim is cleaned out and old sealant removed.
- 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
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children

Common problems we fix in Bromley
End caps get knocked or pushed by water. Once the seal behind them fails, they drip.
If you can see any of these, it’s time to have the joints looked at:
- Internal damp traced to a gutter joint
- Drips from gutter joints and end caps
- Stop ends leaking at the end of a run
- Streaks down the brickwork from a leaking joint
Historic houses such as Much Hadham Palace, about 1.4 miles south-east, show how far back building around Bromley goes.

- Is the old sealant removed completely?
- Which sealant they’ll use, and why
- Are they insured?

Different surfaces, different methods
Gutter joints
Most gutter leaks start at a joint between sections. We clean, dry and reseal them.
Garage door frames
The joint between frame and brickwork moves and weathers. We use a sealant made for outdoor joints.
DIY sealant or a professional job?
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Walls and rooflines in Bromley
Historic houses like Much Hadham Palace (about 1.4 miles south-east) are a reminder that the area around Bromley 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Bishops Stortford station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
