A visit to Portchester is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we agree which joints need sealing.
- We clean out each joint.
- We make sure everything is dry.
- The sealant is applied and finished.
- We check our work before we leave.
How to prepare

Gutter sealing in Portchester
Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where one is available. We’re often asked to deal with water dripping where gutter sections meet and damp on an inside wall under a dripping gutter, across roofline trims, gutter end caps and gutter joints.
In and around Portchester, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
Each job carries a 12-month guarantee.

Do you need gutter sealing in Portchester?
Gutter joints rely on seals that age. Temperature changes make gutters move, and old seals crack or slip.
Look out for any of the following:
- Earlier gutter repairs that have peeled off
- Open joints in fascias and soffits
- Drips from gutter joints and end caps
- End caps that drip every time it rains
Schools such as Castle Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before you book
- What the quote includes, VAT included or not
- Whether you can choose the colour
- When the joint can take water or movement
- How the joint is cleaned and prepared
Why act early in Portchester
Sealing over a dirty, wet joint is a quick fix that rarely lasts, but it soon lets go. Proper preparation is the difference. In an older home around Portchester, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.

Portchester buildings and the weather
Portchester is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on gutter, fascia and roofline joints, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Portchester station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How we quote for gutter sealing
Every job gets its own quote. This is what makes a difference:
- The number of rooms or windows
- How much there is to do
- Whether old sealant or filler has to be cut out
- The product the joint needs
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before any work starts.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- The type of property
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
- Any access issues, like height or stairs
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Deal with a drip before winter
- Get a dropping gutter looked at quickly
- Look at the gutters while it’s raining
- Clean out the gutters once or twice a year
Leave the new sealant to cure as we advise and avoid disturbing it.
