Aftercare tips
A little care helps the new joints last. Our advice:
- Check that water runs out of the downpipes
- Check fascia and soffit joints for gaps
- Get leaks sealed before the wet months
- Rest ladders on the wall, not the gutter
Keep the gutters clear of leaves and moss, so water drains away past the joints. Water left in a gutter tests every joint.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards.
Gutter sealing in Haslar
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter is broken or sagging, we will tell you. We are often asked to deal with old gutter sealant that has let go and dripping gutter ends, across gutter end caps, garage door frames and roofline trims.
External sealant needs dry, clean surfaces, so work around Haslar is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months, in Haslar and everywhere else we cover.

Haslar questions
Is gutter sealing in a coastal place like Haslar any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you help a landlord with a rental near Portsmouth Harbour station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Will sealant fix a dripping gutter joint?
Normally, if the gutter is sound. We clean and dry the joint before sealing so the seal holds.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Do you seal gaps in fascias and soffits?
Yes. We seal open joints along fascias and soffits in a matching colour.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Water backing up from a blocked pipe
- Cracked, split or warped gutter sections
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Haslar buildings and the weather
Haslar is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near St Francis, older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as Haselworth Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Portsmouth Harbour station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.
