Why it’s worth doing now in Newton Valence

Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right compared with treating damp later. Around Newton Valence, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Gutter sealing in Newton Valence

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’ll tell you. Common call-outs are for damp patches inside below a leaking gutter and wet patches on the wall under a gutter joint, across gutter joints, gutter end caps and uPVC fascias.

Older homes in small places like Newton Valence may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.

A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Aftercare tips

Joint life depends on how it’s used and looked after. We suggest:

  • Look for streaks or damp on the wall below gutters
  • Check the gutters during heavy rain
  • Don’t leave a sagging gutter
  • Clean out the gutters once or twice a year

Have a look at the gutter during a downpour. Drips are easiest to spot while it’s raining.

Split sealant on fascias and trims lets water in behind. Resealing early protects the boards and the wall below.

Can you do several jobs on one visit?

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

What guarantee comes with the job?

All our work carries a 12-month guarantee.

Is sealing fascia joints something you do?

Yes. We seal open joints along fascias and soffits in a colour to suit.

Will sealant fix a dripping gutter joint?

Generally, if the gutter is sound. We clean and dry the joint before sealing so the sealant bonds.

Is it OK to seal over old sealant?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.

The process

We keep the work tidy and contained to the area we’re working on. The job generally takes a few hours, depending on the number of joints and the access, and we tell you how long to leave it before we go. In a small place like Newton Valence, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First, we find the drip and check the gutter isn’t cracked or sagging.
  2. The joint or trim is cleaned out and old sealant removed.
  3. We make sure the joint is dry before sealing.
  4. An exterior or gutter sealant is applied to the joint.
  5. We look along the gutter and clear debris around the joints.

How to prepare

  • Let us know about stairs, lifts or work at height
  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about any water getting in

Advice

Common problems we fix in Newton Valence

Sealant laid on a wet or dirty joint fails early. Rushed repairs often do not last long.

Any of these means the joints need attention:

  • Failed sealant on a garage door frame
  • Earlier gutter repairs that have peeled off
  • Stop ends leaking at the end of a run
  • Water dripping where gutter sections meet

If you let a flat or house near Alton station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Before booking anyone

  • Who turns up on the day
  • Whether they’re fully insured
  • Is the old sealant removed completely?
  • Whether VAT is included

Should I try it myself first?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
