Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, 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.
How we handle gutter sealing in Sydenham
Across Sydenham, we reseal gutter joints, end caps and roofline trims. Low-level work is straightforward and if it’s higher up, let us know and we’ll confirm what access is needed.

How long does the job take?
A typical job takes an hour or two for a few joints, longer for a full run. Your quote will say how long we expect yours to take.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How much does gutter sealing cost in Sydenham?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Leave it or put it right?
You do not 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. In a small place like Sydenham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins.

What gutter sealing looks like in Sydenham
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. With historic houses such as Adwell House (about 2.4 miles south-west) nearby, there’s older building stock in the area around Sydenham as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Do you need gutter sealing in Sydenham?
A sealant applied to a damp or dirty joint won’t bond. Some quick repairs peel off within a season or two for this reason.
Common reasons people contact us include:
- Cracked sealant along roofline trims
- Quick sealant fixes on gutters that didn’t last
- Streaks down the brickwork from a leaking joint
- Water dripping where gutter sections meet
For landlords with property near Haddenham & Thame Parkway station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
Questions to ask before you book
- Whether VAT is included
- How long to leave it before use
- How the joint is cleaned and prepared
- Whether they’re fully insured
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Clear leaves and moss from the gutters
- Don’t leave a sagging gutter
- Look along the fascias for open joints
- Deal with a drip before winter
Keep downpipes clear, so water can get away. Blockages push water back along the gutter.
Rain getting in round a garage door frame can damage what’s stored inside. A reseal sorts it.
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours, depending on the number of joints and the access. Somewhere as small as Sydenham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at where the water is coming from and check the gutter is not broken or sagging.
- The joint or trim is cleaned out and old sealant removed.
- The joint is dried, because sealant will not bond to a wet surface.
- An exterior or gutter sealant is applied to the joint.
- The run is checked and any debris near the joints is cleared.
Before we arrive
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
