Gutter sealing in Highfield

Gutter sealing for homes and businesses in Highfield

It’s easy to live with a dripping gutter joint, but the water lands on the same spot every time it rains. Sealing it is quick if the gutter is otherwise in good order. Typical jobs include water running down the wall below the gutter and rain getting in around a garage door, on garage door frames, gutter joints and roofline trims.

Homes around Highfield range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.

Whatever the size of the job, you get the same 12-month guarantee.

How it works

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes anything from an hour or two to a few hours from start to finish. A visit to Highfield 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.

  1. First we agree which joints need sealing.
  2. Each joint is cleaned and any old sealant removed.
  3. We make sure everything is dry.
  4. We apply exterior or gutter sealant and finish it neatly.
  5. We check our work before we leave.

Getting ready for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • On commercial sites, let us know about site rules
  • Let us know about stairs, lifts or work at height

Advice

What the job involves on each surface

Soffit joints

Soffits sit under the eaves, where joints can open up. They’re sealed to tidy the line.

Garage door frames

Resealing a garage door frame keeps rain and draughts out.

Should I try it myself first?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

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.

Highfield: your questions answered

Will you come out to Highfield?

Yes. Highfield is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you help a landlord with a rental near St Denys station?

Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.

Do you guarantee gutter sealing?

There’s a 12-month guarantee on every job, gutter and fascia work included.

Is there any odour?

There can be a smell while the sealant cures, but it fades. Ventilation helps.

Do you clean gutters?

We clear what’s around the joints we work on. Full gutter cleaning is a separate job.

How long should I leave it?

Different products cure at different speeds, so follow the cure time we give you when we finish.

Do you hold any approvals?

Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.

Where is Mr Mastic based?

We work from Crawley. We cover Highfield and the rest of Southampton, along with the rest of our area.

What we can’t put right

New sealant can’t fix everything, and we’ll tell you before work begins. Sealant won’t put right:

  • Cracked, split or warped gutter sections
  • Downpipes that are blocked or broken
  • Leaks from the roof rather than a joint

Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

Surfaces we seal

  • Roofline trims
  • Gutter joints
  • Soffit joints
  • uPVC fascias
  • Gutter end caps
  • Garage door frames

Quotes for gutter sealing in Highfield

There’s no set price list, because no two jobs are the same. What we look at:

  • Working hours on commercial sites
  • Whether there’s mould to deal with
  • The product the joint needs
  • The number of rooms or windows

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

What to tell us for a quote

To make quoting easier, please include:

  • Any previous sealing or DIY work
  • A few photos by email, if you can
  • Access, such as stairs, a lift or height
  • The problem you’ve noticed

To get a quote, ring 0345 464 0079 or drop us an email with the location and a short description of the problem. We’ll give you a clear price before any work starts.

For landlords and businesses

We also work for property managers and facilities teams in Highfield and across Southampton. Several sites can go on one quote, and we’re fully insured for the work.

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Highfield buildings and the weather

Highfield is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Schools such as Highfield Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Highfield Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Highfield is about 1 mile north of Southampton, in Southampton. Every kind of property in Highfield can book us for gutter sealing, old or new, large or small. The work is guaranteed for a year. Across Southampton, we cover 40 places, and Highfield is one of them.

What we’re called out for in Highfield

Gutter joints depend on seals that wear out. Sun and cold make the gutter expand and contract, and old seals crack or slip.

It’s worth asking for a quote if you see:

  • Old sealant on roofline trims that has split
  • Garage door frames letting rain in
  • Water dripping where gutter sections meet
  • Earlier gutter repairs that have peeled off

Letting a property close to St Denys station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Questions to ask before booking

  • Are they insured?
  • What happens if the job turns out different
  • How long the guarantee is
  • Whether the sealant suits the joint
