Gutter sealing for homes and businesses in Rowstock
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. We seal them in a colour to suit where possible. Common call-outs are for wet patches on the wall under a gutter joint and earlier gutter repairs that have peeled off, across uPVC fascias, gutter joints and garage door frames.
External sealant needs dry, clean surfaces, so work around Rowstock is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What we’re called out for in Rowstock
Sealant on fascias and trims weathers like any outdoor joint. It goes hard, cracks and pulls away over time.
Keep an eye out for these signs:
- Old gutter sealant that has let go
- Damp patches inside below a leaking gutter
- Old sealant on roofline trims that has split
- Streaks down the brickwork from a leaking joint
In the older streets around Church of St Matthew, an extension built onto an older house moves differently, and the joint between them takes the strain.

FAQs for Rowstock
Will you come out to Rowstock?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do gutter sealing in Rowstock?
Yes, Rowstock is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is it possible to stop a gutter joint dripping with sealant?
Often, yes. Cleaning, drying and resealing the joint normally works. If the section is split or warped, it needs replacing.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Can you seal fascia and soffit joints?
Yes. We seal the joints, not replace the boards and we will let you know if a board has failed.
Outside joints around Rowstock
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Harwell Primary School, its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Didcot Parkway station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Leave it or put it right?
Sealant won’t clear a blocked downpipe. We check the cause first and tell you if something else is needed. Around Rowstock, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

What the job involves on each surface
Gutter end caps
Drips from a stop end run down the brickwork. It’s a small job to fix.
Garage door frames
Garage door frames let rain in when their sealant fails. We cut it out and reseal.
DIY sealant or a professional job?
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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
