How we handle gutter sealing in Rush Green

We don’t replace gutters, fascias or roofs. What sealant does is close joints; it will not fix a broken bracket, a cracked section or a blocked downpipe. Typical jobs include damp on an inside wall under a dripping gutter and trim joints where the sealant has failed, on gutter end caps, soffit joints and garage door frames.

External sealant needs dry, clean surfaces, so work around Rush Green is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.

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

How to look after the new joints

A little care helps the new joints last. We recommend:

  • Keep an eye out for wet patches below a joint
  • Clear leaves and moss from the gutters
  • Check the gutters during heavy rain
  • Keep ladders off the guttering

Make sure downpipes aren’t blocked, so water can get away. A blocked pipe backs water up to the joints.

If an end cap is dripping, deal with it before winter. A winter of drips can lead to damp patches.

Outside joints around Rush Green

Historic houses like Knebworth House (about 2.1 miles south-east) are a reminder that the area around Rush Green has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Schools such as The Thomas Alleyne School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Stevenage station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

FAQs for Rush Green

Will you come out to Rush Green?

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

Do you work for landlords with property near Stevenage station?

Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Can you seal over the old sealant?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

Can a leaking gutter joint be sealed?

In many cases, yes. A clean, dry joint resealed with gutter sealant generally stops the drip. A split or warped section needs replacing.

How do I get a quote for gutter sealing in Rush Green?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Should I try DIY first?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

Do you hold any approvals?

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

Can I choose the sealant colour?

Yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before any work starts.

How it works

The work is kept neat and contained to the area we are working on, so you can get on with your day. The job generally takes anything from an hour or two to a few hours, and we explain the cure time before we leave. In a small place like Rush Green, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by tracing the leak and checking the gutter itself is sound.
  2. Old sealant and dirt are removed from the joint.
  3. The joint is dried, because sealant won’t bond to a wet surface.
  4. Gutter or exterior sealant is applied and finished.
  5. We check the run and clear any debris we find while we’re there.

How to prepare

  • Tell us about any previous sealing or DIY attempts
  • Tell us about any water getting in
  • Plan for the work area to be out of bounds to pets and children

Why act early in Rush Green

If the problem is a blocked downpipe, sealing won’t help. We check the cause first and tell you if something else is needed. Around Rush Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Do you need gutter sealing in Rush Green?

End caps get knocked or pushed by water. Once the seal behind them fails, they drip.

Any of these means the joints need attention:

  • Gaps along fascia and soffit joints
  • Rain getting in around a garage door
  • Quick sealant fixes on gutters that didn’t last
  • Drips from gutter joints and end caps

Knebworth House, about 2.1 miles south-east, is one of the historic houses in the wider area around Rush Green, and older homes nearby need a sealant that suits their walls.

Choosing a sealant specialist

DIY sealant or a professional job?

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.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
