Avoid MBL Construction Ltd and Marin Bernevec – Extremely Disappointing Experience

Hiring MBL Construction Ltd, managed by Marin Bernevec, turned into a deeply regrettable experience during our home renovation in 2023.
Despite providing clear written instructions, we encountered numerous issues that significantly impacted our property and finances:

* Significant Property Damage: Interior walls were damaged, our original 1860 sash window frames were cut without permission, and ceilings were lowered by 30cm instead of the requested 10cm. Incorrectly ordered radiators also resulted in extra, unrecoverable costs.

* Damaged Belongings: Despite assurances, several valuable pieces of furniture and personal items were damaged due to inadequate protection during the work.

* Structural Concerns: Flooring was raised by 16cm rather than levelled, which altered room proportions in our Victorian property. Large holes were left in the floor when the original boards were removed, creating hazardous conditions.

* Unsafe Workmanship: Plumbing and electrical work had to be completely redone by another contractor. Two of the ceilings installed later collapsed, posing a serious safety risk to subsequent builders.

We incurred over £46,000 in additional costs including repairs, rent for temporary accommodation, storage, and hiring a new contractor while also preparing for the arrival of our baby.

We pursued a small claims court case and won, but the director did not attend the hearing and compensation remains unresolved.

Throughout the project, we experienced a lack of continuity, with different workers arriving on site each day.

This raised serious concerns about accountability and consistency in the work carried out.

We strongly advise anyone considering MBL Construction Ltd to carefully reconsider. Our experience was not only financially and emotionally exhausting, but also left us with lasting stress and disruption during a vulnerable time.

We can only hope that sharing our experience helps others avoid a similar situation.

1.Significant Property Damage: Interior walls were damaged, our original 1860 sash window frames were cut without permission, and ceilings were lowered by 30cm instead of the requested 10cm. Incorrectly ordered radiators also resulted in extra, unrecoverable costs. - remove windows frames to add pipes from walls and after plan to fix back (pipes to radiators better to add from walls not from foor,is look better)

2.Damaged Belongings: Despite assurances, several valuable pieces of furniture and personal items were damaged due to inadequate protection during the work. - Nothing damaged ,if have any damage have to show these ,or to arrange expert to analyse property and damaged things

3.Structural Concerns: Flooring was raised by 16cm rather than levelled, which altered room proportions in our Victorian property. Large holes were left in the floor when the original boards were removed, creating hazardous conditions. - After done demolition ,we depistate all house go down from one side 16cm,we give price to correcting problem ,to add on original joints on top to make level(to change joints not posible because another flat on ground floor ) - We start works ,client stop job and arrange someone for floor wich was extra not in agrement - Not respond on phone to confirm when we continue job - After some time ask to return all money 

4.Unsafe Workmanship: Plumbing and electrical work had to be completely redone by another contractor. Two of the ceilings installed later collapsed, posing a serious safety risk to subsequent builders. - Plumbing and electricity was done not totally (just first fix done ) - We do plumbing and electricity with same electrician and plumber in same building on ground floor (and after that much time not have any problem,everything is working perfect 

We incurred over £46,000 in additional costs including repairs, rent for temporary accommodation, storage, and hiring a new contractor while also preparing for the arrival of our baby. - I received some money - I cover : - Demolition (clear house and put everything in skip) - plumbing first fix labour and first fix materials - Electricity first fix labour and first fix materials materials - Install new plasterboard ceilings (around 100m2) all materials I provide 
 5.We pursued a small claims court case and won, but the director did not attend the hearing and compensation remains unresolved. - I have few calls from claim officer and explain all situation and not received any penalty or anything 

6.Throughout the project, we experienced a lack of continuity, with different workers arriving on site each day. - In 2 weeks from start was done all first fix plumbing and electricity,new ceilings,demolition - Skip and all first fix materials included 

This raised serious concerns about accountability and consistency in the work carried out. - If you don’t stop job and discuss correct with me everything was different - Your wife speak angrily -i asked to complete job and no one respond on phone ,after some time ask for all money to return. In these case have to arrange expert for cecking all works done if is correct fixed or not 

7.We strongly advise anyone considering MBL Construction Ltd to carefully reconsider. Our experience was not only financially and emotionally exhausting, but also left us with lasting stress and disruption during a vulnerable time. - In 2 weeks was done a lot of work and buy a lot of materials - until he entered the house and without seeing those inside he started causing trouble
 8.We can only hope that sharing our experience helps others avoid a similar situation. -a bad experience with aggressive clients -I don't recommend a client like John to anyone. Same flat in same building was done properly and to now around 4-5 years everything is working fine without any issues

This is the second job I have had with Marin and the team in to do. They installed a fabulous kitchen for me 2+ years ago and I can't praise their work highly enough. This time they transformed my front garden, wall, pathway, porch and bay window from something that looked like it belonged to a condemned building into a home I'm proud of! I was so impressed with the quality of their work, which they delivered well within budget. There is such an attention to detail and a real pride in what they do. I wouldn't hesitate to recommend them to anyone, for any job large or small. I would happily have them back again for any project in my home. More...

Marin the boss and his team were able to carry out work related to a property in the development according to the prescribed work by the surveyor.
The owner of the property was satisfied with the completed work. Standard of the end product was very good.
They left the place tidy. Their pricing was reasonable.
Marin does not do the actual work but he is accommodating and always is present when required to assist.
They are intending do carry out more work in the development.

We worked with MBL on a flat refurbishment. The outcome was satisfactory and within our budget plan despite some design changes from our side.

Most of the work were done by subcontractors, which were of varying quality. Those that were not satisfactory were replaced and covered by MBL. This did however result in delay of time.

Majority of the work completed more or less on time, with the exception of joinery items that were contracted to a company recommended by Marin, this resulted in the longest delay in the project.

Electrical and plumbing work were done well.

Since most of the work were done by subcontractor, it required our attention and presence during the work to manage the progress of the project, which might not be possible for others to do.

We don’t work with that furniture company anymore. However few changes of wardrobes drawings and delays on confirmation of colour and design of wardrobes from client, caused delays on delivery of furniture. Also, client add 25-30% work on top of the initial agreement , and do changes on job till works move Good experience with friendly clients !

I feel compelled to warn others to avoid MBL Construction and Marin Bernevec at all costs.

I engaged him to work on the refurbishment of my flat but from the outset, it became clear that Marin himself had very little involvement in the actual building work. He was rarely on site, and instead he subcontracted every aspect of the job to others, who appeared to lack the necessary skills or oversight to deliver a passable standard of work.

Tasks were started in a completely ad hoc manner with no sense of structure, planning, or basic project management. The lack of basic building knowledge was apparent at every stage, with mistakes mounting faster than they could be addressed. The quality of the work carried out was poor.

Health and safety were treated with disregard. During the course of the project, the glass hob of my induction oven was smashed, multiple plants were killed, and my possessions were handled carelessly. It was clear that neither Marin nor his subcontractors had respect for my property or the space they were working in.

I received multiple complaints from both my neighbours and the building management regarding the conduct of the workers, the mess they left behind, and their general lack of professionalism.

Marin initially stated that the project would take seven weeks. However, after seven weeks, minimal progress had been made. Instead of taking responsibility for his non-existent project management, he blamed delays on materials arriving late—a claim that was simply untrue.

The level of unprofessionalism throughout this project was staggering. Communication was terrible, often leaving me in the dark about what was happening on site. On several occasions, I even received threatening messages and two requests for money from Marin ahead of agreed milestone payments. One of his subcontractors (Alexander) directly approached me on site asking for money, as it was evident Marin had not been paying them.

Furthermore, Marin consistently lied to me about the progress of the work, providing false assurances and misleading updates. It became abundantly clear over time that he is an entirely untrustworthy contractor who cannot be relied upon to deliver on his promises.

In the end, I was left with no choice but to cancel the project halfway through. The quality was so poor, and the situation had become so untenable, that continuing would have been throwing good money after bad. I would rather take the financial hit than working any more with MBL construction.

I only wish I had seen John's review beforehand, as his experience mirrors mine. MBL Construction, under Marin Bernevec, operates in a manner that can only be described as reckless, bordering on dangerous.

We worked with MBL in Septembr and our experience was mixed. On one hand the builders were friendly and very quick (~4 weeks) for flat renovation including kitchen, bathroom toilet etc. ,., we were on a tight timeline so they were very forthcoming and willing to meet us on the timing side. On the other hand there were some mistakes and issues that have left us in a worse off position long-term, such as completing our LVT flooring over very uneven floor surface in our corridor, resulting in a potentially very costly mistake for us in the future to replace if the flooring rips, potentially thousands if we have to replace all the flooring all over again. As a temporary fix, we've now had to get a rug to lay over there to soften foot traffic.

Another example is installing our shower without checking if the water drained. The builders had suggested making the access to our waste pipes smaller (which were behind a access door originally), but since they hadn't checked if the water ran and did not want to come back to fix it, we have now had to hire plumbers to fix the issue, which has not only been more costly but more time-consuming given that the access panel we have is now a lot smaller based on their suggestion.

Overall, if you are experienced with renovations and have the time to supervise, they are efficient and quick, and will get the job done. It would just be important to supervise on issues like the ones I mentioned above (unevenly layered flooring, a shower installed on pipes that don't drain etc.,.).

Marin and team have really done a wonderful and clean job. They have completed a full house refurbishment (5 bedroom house) in the span of 7 weeks. The works include removing the existing staircase, remodeling and installing a new Staircase. Installing Kitchen and Diner Area inclusive of all pipework and accessories from a new un-vented cylinder, Extending an existing bathroom and remodeling the other bathroom with new appliances, tiling and plumbing works, Creating a new utility area including drainage and water supply, Installing new lighting throughout the house and additional sockets where necessary, Loft boarding and creating storage area with access ladder, Installing new in-built wardrobe in master bedroom, Replastering where required and painting the overall house. The cost comparatively was cheaper and also included the first fix materials. Will need to give special credits for Stan and Ion who was the forefront team who done all the works and delt with us on day to day basis. Marin was always available on the phone if there were any issues to resolve. Overall a great job by the team. More...

Marin helped me to renovate my house and he organised, arranged and done the following for me:
Plumbing
Electricity
New bathroom
New kitchen
Painting and decorating the entire house
New laminate flooring

Of all the quotes I received for the renovation, Marin came in the best and most competitive, by a large amount, so it was good value for money!

The project was done in the agreed time and budget, and my house looks great now!

What I like most about working with Marin is that he is always available to answer any questions and resolve any issues and problems that come up.

Renovation is always a big project, and issues do come up, and I like that Marin was there to address and solve all of them promptly and efficiently.

On top of that, Marin was very keen and quick to help out with other things that came up such as for example great value for money contacts for waste removals, etc.

I would hire Marin again for other projects!

Marin is a very dedicated professional who takes pride in his work. His finish is excellent. He did wallpaper, coving, painting walls and ceiling, glossing skirting, window pane, radiators, along with filling and sanding my living room and dining area. He is also very respectful, commited and dependable. Marin worked into the late hours of the evening to finish the job on time. A true professional who I will be recommending to friends and family and using his services again. More...

I recently hired MBL to paint my flat and I couldn't be happier with their services. Not only did they expertly paint every room to my satisfaction, but they went above and beyond by offering to carry the paint from the shop and staying until late to ensure the job was completed in a timely manner. The team was professional, courteous, and friendly. I would highly recommend them to anyone looking for quick, efficient, and good quality painting services. More...
