Gutter sealing for homes and businesses in Streatham Park
A lot of gutter leaks come down to one tired joint. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter is broken or sagging, we will tell you. If you are dealing with damp on an inside wall under a dripping gutter and old gutter sealant that has let go, we can put it right, on soffit joints, gutter joints and roofline trims alike.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in Streatham Park, check the lease for who looks after the outside.
All of our work is guaranteed for twelve months.

FAQs for Streatham Park
Do you work for landlords with property near Streatham station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you cover Streatham Park for gutter sealing?
Yes, Streatham Park is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Do you clean gutters?
Only around the joints we seal, so the sealant can bond. A full gutter clean is a separate job.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Do you seal gaps in fascias and soffits?
Yes, it’s a common job. Each joint is cleaned and sealed with a suitable exterior sealant.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Aftercare tips
A little care helps the new joints last. Our advice:
- Look at the gutters while it’s raining
- Get a dropping gutter looked at quickly
- Sort out a dripping joint early
- Keep downpipes clear
Have a look at the gutter during a downpour. Drips are easiest to spot while it’s raining.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job while the frame is sound.
How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours, depending on the number of joints and the access, including the tidy-up. In Streatham Park, 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 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.
- 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
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
