How we handle gutter sealing in Kemprow
Failed sealant round a garage door frame lets rain blow in. We cut out the old sealant and reseal the frame with an exterior sealant. If you are dealing with quick sealant fixes on gutters that didn’t last and damp patches inside below a leaking gutter, we can help, whatever the surface.
External sealant needs dry, clean surfaces, so work around Kemprow is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Whatever the size of the job, it’s backed by our one-year guarantee in Kemprow and across Hertfordshire.

Kemprow questions
Do you cover smaller places like Kemprow?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Radlett station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
What guarantee comes with the job?
Our one-year guarantee covers every job.
What do you need from me for a quote?
A short description and the location. If we need more, we will ask.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
How long does the job take?
Typically it takes anything from an hour or two to a few hours. Bigger jobs take longer, and we will say how long yours will take.
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, while a short indoor joint may be within reach.
What the job involves on each surface
Roofline trims
Trims along the roofline are often finished with sealant. When it splits, water can get behind.
Garage door frames
Garage door frames let rain in when their sealant fails. It’s removed and renewed.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Aftercare tips
So the new joints stay in good condition:
- Check that water runs out of the downpipes
- Glance at the soffit joints now and then
- Clean out the gutters once or twice a year
- Keep ladders off the guttering
Make sure downpipes are not blocked, so water can get away. Blockages push water back along the gutter.
A leaking garage frame lets water reach stored items. Resealing the frame is a quick job.
