 Trustindex verifies that the original source of the review is Google. Found J&I through a Google search. They were very responsive to my questions and easy to book with. The cleaner they sent did an amazing job on the bathroom deep clean, even managed to remove stains I thought were permanent. She was very professional and extremely polite. Brought all their own supplies and even a step ladder to reach the ceiling. I would totally recommend J&I for deep cleaning.

 Trustindex verifies that the original source of the review is Google. They did a fantastic job for end of tenancy clean.  The inspector was impressed and, so far, not had an extra charges from the letting agency. They arrived bang on time and the communication with the office (i had to change the original booking) was excellent.  The price was very competitive compared to online search results.  Would especially recommend if you live in Quintain flat.

She literally cleaned from head to toe including inside my bathroom cabinet and sink vanity drawers.  I would absolutely use this company again and am absolutely happy to recommend to others.

 Trustindex verifies that the original source of the review is Google. J&I Cleaning were recommended to us by a friend, work from a High Street office, gave me a reasonable quote over the 'phone. They require full payment in advance (!) but... recommended and office based,  so... Their worker turned up promptly, got on with the work, moved furniture carefully and appropriately put it back and did a very good job, all within less time than had been predicted. We think money will spent

 Trustindex verifies that the original source of the review is Google. The cleaners did an excellent job on my kitchen. I had alot of things and so they ran out of time, but I recommend them to others, for they work so well and to a very high standard. I especially love the cooker and microwaves. I would use them again.

Cleanliness Quality Classification – BS EN 15780 and BESA TR19

At J&I Cleaning Services Ltd, we follow the guidance of BS EN 15780 and BESA TR19 when assessing the cleanliness of ventilation systems. These classifications help determine the appropriate level of cleanliness based on how each space is used:

Low: Suitable for rooms that are used occasionally, such as storage areas and technical rooms.
Medium: Appropriate for more frequently used spaces including offices, hotels, restaurants, schools, theatres, care homes, retail areas, exhibition centres, sports venues, general hospital areas and standard industrial working zones.
High: Designed for spaces that demand stricter air quality, such as laboratories, hospital treatment rooms and high-grade office environments.

Additional Inspection Services Provided

We also carry out a range of other inspections to support the safety and compliance of ventilation systems:

Fire and Smoke Damper Inspections: Our trained specialists conduct fire damper inspections in line with BS 9999:2017. These assessments are essential for ensuring dampers operate correctly and help prevent the spread of fire and smoke throughout a building.
Accessing Ventilation Systems: Inspections are carried out through existing access panels where possible. If further entry points are needed to complete the inspection, we can install additional ventilation access doors or openings without disruption to your system.
CAD System Mapping: We can update CAD drawings to show the layout and key components of your ventilation system. These can include locations of access panels and test points for ongoing maintenance.

Ventilation Inspections FAQs

How often should I have my ventilation system inspected?

We recommend having your ventilation system professionally inspected at least once a year to ensure it continues to operate efficiently and safely. More frequent inspections may be necessary for high-usage or industrial environments.

What are the signs that my ventilation system needs an inspection?

Signs include unusual noises, reduced airflow, increased energy bills or poor air quality. These may indicate that your system is due for an inspection to identify and address any underlying issues.

Can an inspection improve the energy efficiency of my ventilation system?

Yes, regular inspections can identify inefficiencies within your system, allowing for adjustments or repairs that improve performance and reduce energy consumption, leading to cost savings and environmental benefits.

J & I Cleaning Services carried out an end-of-tenancy deep clean at my rental property in Ruislip on 30/8/24. Their team of four ladies worked industriously and effectively for three-and-a-half hours, leaving the house immaculate from top to bottom. I was delighted with the result, as were the landlord and letting agent. I would have no hesitation in recommending J & I for any, and all, cleaning requirements.Rick Absalom

The best service I have ever had. Not only they have experts to professionally do the job, but also very humble and friendly cleaners. For the first time i am seeing they finish the job in given hours and cleaning everything. Specially Edyta, she is an expert in doing her job, left no spot and did everything in less than two hours which is a miracle. If you want to have a regular great cleaner, consider her as she is the best.

We are Grilled Grub based in Maidenhead and as you can imagine need a cleaning company to make sure our equipment is in the best condition possible. We have used J and L for our business to clean our extraction system twice now, the staff were really professional, the job done fantastic and we would personally like to thank Elizabeth and the staff involved in the cleaning process. We thoroughly recommend them as a business and will definitely use them in the future.

I've had Diana cleaning my apartment for over a year now, and she's fantastic! She's not only thorough in her cleaning but also reliable and trustworthy. She always goes the extra mile to make sure everything looks great, and her attention to detail is impressive. Plus, she's always punctual and respectful of my space. Highly recommend her if you're looking for someone who's professional and does a great job every time!

J&I were very efficient but the best thing they did was to assign Diana to clean our flat weekly for over two years until we moved away from London. We can’t praise Diana enough and J&I for their efficiency.

I would not hesitate to recommend J&I Cleaning, their team was punctual, polite and professional throughout the whole deep clean of our production kitchen and ventilation system.

I must say, J&I Cleaning provided an absolutely sterling service. From my initial chat with Elzbieta on WhatsApp to the thorough deep clean their team carried out, the professionalism was top-notch. With a brigade of over eight dedicated chaps, they ensured every nook was pristine. Their determination to make certain I was wholly satisfied before finishing up was commendable. Given their splendid service, I'd heartily recommend them to anyone in need. Splendid job, indeed!

They arrived a little late but boy did they make up for it! Finished 2 hours early and the kitchen was the cleanest we have seen it since initial installation 13 years ago! They cut an extra access panel into our vent to make future cleaning easier, too.Their office team were polite, well informed and helpful.11/10

Very happy indeed to return to our spic and span flat. Agnes had managed to clean things that I’ve been trying to clean for ages, like my hob. This was a treat from my daughter following both my husband and I having been in hospital. However I am so pleased with Agnes that I will be in touch to see if she can come on a regular basis. Many thanks

Two charming, friendly and respectful young ladies did a Deep Cleaning of my flat. They were very professional.and hard-working. They paid close attention to detail, going beyond the Call of Duty in using their initiative to clean extra items, like the oven, leaving it sparkling! I have many possessions, some fragile and breakable, which require very careful dusting, and these ladies worked with great care and respect for my belongings. They vacuumed my carpets and rugs quickly, but thoroughly and efficiently. They scrubbed the toilets and tiled floors till they shone! My home has never been so clean, and I shall certainly use J&I Cleaning again. I have already recommended their Services to my family and friends. Thank you, Alina and Joanna! Your very satisfied client, Kathleen
