Very carefully, score along the top of the sash and the upper window frame.

Very carefully, score along the top of the sash and the upper window frame.

Have you been dealing with sticky windows and don’t know where to turn? Perhaps you didn’t know you could prevent this with some simple DIY.

Here at Ventrolla we treat existing wooden sash windows to remove any rot and improve operation, but we thought we would share some handy hints and tips to help maintain those sashes before the experts need to move in:

  1. Firstly, you should check that the sash isn’t just painted closed. Take a utility knife and, very carefully, score along the top of the sash and the upper window frame. If the sash still doesn’t open then continue with the following steps.
  2. Check there is nothing hindering the sash anywhere else. Take your utility knife and score around the whole sash and casing. Now try to wiggle the window. It may help to use the knife at the same time, sliding the knife between the sash and top to try and free it. Again, if this doesn’t help proceed with the following steps.
  3. You now need to try unsticking the sash from the outside and check no exterior paint is hindering movement. Use your utility knife between areas that don’t move freely. And remember, ground floor only. 
  4. Providing this has worked, you will be able to see the inner window tracks. Check for any blockages, carefully sand the area and without getting it on the brush pile, apply wax to keep things moving smoothly.

These points mostly cover painted shut windows, but what if humidity is the problem? This is where simple home appliances will come in useful to help with swelling.

  1. Set a hair dryer to a low heat and aim it at the sash and window frame, indoors. 
  2. As the window dries out, wiggle it until it moves freely. 
  3. Now just clean out the tracks and again being careful not to get it on the brush pile, rub wax in the tracks to keep the window moving freely.

Some further points:-
If some of the paint feels chunky or you notice other obstructions carefully use sand paper to stop this becoming a problem.

Keep the tracks free from dirt and debris to keep the window operating smoothly.
In the summer months, the combined heat and paint on your windows mean they are likely to swell.

Ventrolla are here to offer a helping hand.

Ventrolla are here to offer a helping hand.

Following the sudden closure of the Green Deal Home Improvement Fund on 24th July, leaving homeowners angry and confused, period window specialists, Ventrolla are here to offer a helping hand.

The Green Deal, a scheme that allows households to benefit from energy-efficient improvements, re-opened in June this year and offered individual households up to £7,600 to install measures such as solid wall insulation and double glazing.

The government claims that the lack of notice on closure was due to “overwhelming popular demand”. However thousands who paid for a Green Deal assessment will now lose out after not registering in time, prompting a formal investigation.

David Greaves, Managing Director of Ventrolla, said: “This news is troubling as the Green Deal’s original aims to help bring properties up to scratch with energy saving improvements and reduce carbon emissions were admirable.”

“Unfortunately the government does not seem to have hit the mark this time and many people will be left out of pocket. Fortunately though, our nationwide network of offices is on hand to provide help and guidance to those affected. ”

“Our energy saving range includes double glazing solutions, as well as draught-proofing using the Ventrolla Perimeter Sealing System (VPSS), which improves a window’s energy rating by up to 30%, reducing energy bills and eradicating draughts and rattles.”

“It is a shame that the Green Deal has not provided the assurance that was originally expected. However we would like to offer reassurance to our customers that there are products on the market in line with the Green Deal aims and that we are available for guidance and advice on 0800 0277 454 or”

Nature Trail and gardens at Horticap

Keen to promote the importance of recycling and minimising waste, period window specialist Ventrolla has been donating its off-cuts and sawdust chippings produced by its joinery shop to support Harrogate-based charity Horticap.

Helping to stoke the centre’s wood burner throughout the winter months, the charity based in Bluecoat Wood Nurseries regularly benefits from the waste materials produced by Ventrolla, which works to heat their greenhouses.

Horticap offers support and employs individuals with learning difficulties. Staff and volunteers at the centre provide training in horticulture, craft work and rural skills such as maintaining the beautiful nature trail and gardens, woodwork and card making.

Some of the students who are supported by, and help maintain the gardens at Horticap.

Joy Allan, Chairman of the Trustees of Horticap, said: “We welcome all donations and wish to thank Ventrolla for their support. Help such as this means we are able to continue our work and provide support for individuals to learn, build their confidence and develop new skills in the community.”

David Greaves, Managing Director of Ventrolla, said: “Horticap is a fantastic local charity and we are delighted to be able to help in any way we can. I would advise anyone who hasn’t been to Horticap already to visit the charming gardens or browse their shop. It is a charity well worth recognition.”

Social-HousingSocial landlords and housing associations are facing huge challenges when it comes to maintaining publicly-owned properties.

Of the 3.3 million homes for social rent in England, around 1.5 million were built between 50 and 100 years ago, meaning many are now reaching an age where major repairs must be considered.

Not only is this putting pressure on maintenance workforces, but a clamp down on public property owners by the Housing and Communities Agency (HCA), regarding procedures and budgets, is making the maintenance process more involved.

The need for greater transparency on spending, driven by the regulator’s value for money standard, means it is becoming increasingly important to have access to services that offer quality, efficiency and cost effectiveness, with long term durability.

Christian Walker, Marketing Manager at period window specialists Ventrolla, said: “We’ve experienced an increase in enquires related to social housing, which is no surprise in light of recent reporting on the sector.”

“More and more of our customers are expressing the importance of future-proofing their homes and investing in products which will last them a lifetime. As a result, we’ve seen many opting for the reinstatement of timber sash windows to replace their ageing plastic or aluminium ones, mainly as timber windows have around three times the lifespan and can increase the value of a period property.”

“What Ventrolla can offer as a solution to this problem is a service and a product which meets the needs of not only the housing associations and landlords, but also their tenants too. As period window specialists, our products respect and retain the design and heritage of old buildings, while also improving their energy efficiency.”

With over 30 years’ experience, Ventrolla offers a nationwide bespoke renovation service for timber sliding sash and casement windows as well as for timber doors.
Its unique service includes draught-proofing with the Ventrolla Perimeter Sealing System (VPSS) and fitting replacement double-glazed sashes that incorporate the patented Sash Removal System (SRS) for easy painting and maintenance.
