Clean Air

Ventilation is not only the best way of preventing condensation in your home, it will also dramatically improve indoor air quality. Most ventilation systems provide health benefits by reducing naturally-occurring Radon gas and carbon monoxide. As well as this, many units are equipped with filters capable of removing up to 95% dust particles and other allergens. This can include pollen filters that can both help you keep cool indoors and enjoy the benefits of fresh pollen-free air. Hayfever sufferers can benefit massively from a place where they can escape pollen and focus on bringing the symptoms under control.

Positive Input Ventilation (PIV)

Positive Input Ventilation (PIV) also sometimes known as positive pressure ventilation work as a whole house ventilation system and create fresh and healthy living environments by supplying fresh, filtered air into a property at a continuous rate throughout.
Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used for purposes of thermal comfort or dehumidification. Positive Input Ventilation or PIV Systems work by encouraging the movement of air from inside to outside from a unit that is usually installed in a loft. These units reduce or eliminate surface condensation altogether by replacing humid stagnant air with fresh filtered air.

Are Positive Input Ventilation Units Noisy?

All of our PIV units are designed to perform with extremely low noise levels, always ensuring the best level of whole house air ventilation is maintained.

Positive Input Ventilation or PIV Systems work by encouraging the movement of air from inside to outside from a unit that is usually installed in a loft. These units reduce or eliminate surface condensation altogether by replacing humid stagnant air with fresh filtered air.

A positive input ventilation system relies on a central unit which is mounted in your loft and connected to the exterior of your house and internal rooms via ducting. As PIV systems require connection to mains electricity and involve the addition of vents into several rooms, they should be professionally installed to ensure that they work correctly and are safe.
In addition to the installation process, it is also important to plan how the PIV system will be configured in your home. During a free home survey, our local ventilation specialists will assess your home to find out exactly what your ventilation requirements are and provide the right solution for your needs.

PIV systems work by drawing air into your home from outdoors rather than actively forcing the air out. This means that the fresh air will mix with the air already inside the house and be warmed by it.
In a well-insulated home, the heat loss will be minimal, and the small additional cost of heating will be offset by the long-term benefits of reducing condensation and the problems that it can cause.

Unlike Positive Input Ventilation Systems (PIV) which actively pull air into the house from outside and use this increase in pressure to force damp air out, Continuous Mechanical Extract Ventilation (MEV) systems rely on a central extractor system which pushes air out of the house to be passively replaced by the fresh air from outside.
PIV systems can be installed in an existing home without the need for extensive building work, which can make them a much better choice in circumstances where you want to avoid the additional cost and inconvenience of a full renovation.

Had a meeting with their surveyor Andrew yesterday 15/02/2022. I have to say he was very professional. Very happy with the quote we have been given and hoping to go ahead with the work early summer. I can’t wait to see the finished product!

“Thanks to Franky, Daniel & Sonny for all their hard work. They have worked beyond expectation”
Mrs J Wilton, Gloucester

Great work on a damp proof course and other bits and pieces. Arrived on time and knew exactly what to do. Leagues above the other quotes. Hope I don’t need you again but would be happy to recommend.

Excellent customer service! James did a very thorough survey and identified a small breach in the tanking in the basement (not fitted by them) He was very knowledgeable and did his very best to find an ‘economical’ solution. He was very honest and I was able to conclude that at this point the cost of repair far outweighed the benefits gained. Should the situation change I would definitely use them.

Christine Lane, Bark review

The Home Building & Surveying Company were excellent in all departments – professional, reliable, well-informed. They resolved multiple residential issues with minimal fuss and would definitely use them again, though fingers crossed I shouldn’t need to!

“I am very pleased with the work done from the initial survey to completion of the damp treatment. I would like to particularly commend Josh & Joe as a team they were courteous, efficient & professional in their workmanship”

Mr Fennell, London

I spoke to Jack on the phone, who was very friendly and professional. Then James performed our survey. I found James and the experience with the Home Building & Surveying Company very refreshing, compared to others I have used in the past. They were very honest in their assessment and responses, with no hidden extras, providing very valuable advice. I am, and will in the future recommend them to anyone with damp challenges.

Booked in quickly and survey was much more in depth then expected. Felt very comfortable in our decision and was a notch above the rest.

Spoke to a very polite and friendly chap called Jack on the phone who explained all about the exterior painting they do, and I decided to have a survey. The surveyor Stuart was very knowledgeable, and I’ve decided to go ahead with them. There’s too many cowboys out there, so it’s nice to see such professionalism from a company for once.

Great company from initial call to completion. Gave quote with no hidden extras, started and finished on time – the finished product looks great. Kris & Nathan were stars of the show, arrived on time, worked hard all day, polite and personable, cleaned up when finished, a credit to the company.

Immaculate, efficient service, it wasn’t a big deal for Luke and his team. Keep up the Good work. Highly recommended.

Andrew White, Google review

I was very please with the work the company has done. I had damp throughout the house so had damp-proofing including an injection of damp course. Given the extent of the job they completed the work efficiently and with minimum disruption. The workmen were always polite and very helpful. The finished work was excellent. Only time will tell if the damp problem has been sorted but the company made it they would come back to fix any issues. I have no doubt they are true to their word and would recommend them to anyone.
