Door replacement – trust experienced professionals through Fix!

Replacing doors in your home or office is a step towards better security, soundproofing, and stylish interior. But how do you choose the right professional for this delicate installation? In 2025, the options are many, and the risks are real. In this article, we will guide you through the entire process, provide practical advice, and modern approaches to finding the best contractor through the Fix! mobile app.

Why does door installation require a special approach?

A door is more than just a panel with hinges — it is a barrier against noise, cold, intrusion, and at the same time an accent in the interior. Its installation requires precision, specific tools, and knowledge of different materials and types of doors. An error in leveling or improper installation can lead to permanent damage or loss of warranty.

What types of doors are most commonly installed in Bulgaria?

  • Interior doors – Laminated, veneered, MDF, HDF
  • Security doors – For entrances, with enhanced security
  • PVC and aluminum doors – Often for bathrooms, balconies, terraces
  • Sliding doors – For spaces with limited room
  • Fire-resistant doors – For public and industrial facilities

Each type requires a different methodology, fasteners, and tools.

What should we know about materials and techniques?

The choice of a professional should be based on their experience with the specific material and type of door. For example:

  • Installation of laminated and MDF doors: Requires delicate handling to avoid damaging the coating. Must be leveled in three directions.
  • Security doors: Installed to concrete or brick with special anchors, often using polyurethane foam for sealing.
  • PVC and aluminum doors: Requires a professional cutting tool and special profiles for sealing.
  • Sliding systems: Attention to the rails and precise adjustment of the wheels to avoid blocking.

How much 
 does door installation cost?

Prices vary according to the type of door, complexity, and location:

  • Interior door: from 60 to 120 BGN
  • Security (entrance) door: from 150 to 300 BGN
  • Sliding/specialized: from 100 to 250 BGN

In Sofia and major cities, prices are higher due to transportation costs. Always request a quote that includes dismantling, removal of the old door, and finishing work.

How to assess which professional is suitable?

Don't be swayed by price alone. Check:

  • Ratings and reviews – See opinions from real clients on Fix!
  • Qualification and experience – The professional should have experience with the respective type of door.
  • Warranty – Good contractors provide at least a 12-month warranty on the installation.
  • Communication – Ask questions about materials, technique, and completion time.
  • Insurance and contract – Always work with professionals who offer a contract and insurance.

How Fix! makes the choice easier (real example)

Maria from Plovdiv decides to replace 4 interior doors. Through Fix! she posts a request, describes her requirements, and receives 5 offers. She filters by rating, chooses a professional with over 30 successful installations and excellent reviews. In the app, she tracks the entire process, pays securely, and receives an electronic warranty. The replacement is completed in 2 days without surprises.

Creative tips for finding a good professional

  • Ask for innovative installation solutions – For example, invisible hinges, threshold-free installation, digital locks.
  • Request photos from previous projects – See real results.
  • Test communication skills – A good professional will clearly explain the process and offer maintenance advice.
  • Look for verified professionals with a public profile – Fix! provides ratings and execution history.
  • Negotiate fixed deadlines – Include a penalty for delays in the contract.

Locations and specifics: what to consider in your area

In major cities (Sofia, Plovdiv, Varna, Burgas), there is more choice and specialized professionals. In smaller towns, universal contractors are sought, but even there, through Fix!, you can find certified professionals from nearby cities offering transport and delivery.

In new constructions, there are often larger openings and non-standard sizes, which require an experienced installer.

Legal requirements and guarantees

According to the Consumer Protection Act, any door installation by a trader or professional with a company is subject to a minimum guarantee of 


2 years for the product and 1 year for the installation. Request a document for the installation — this is your guarantee in case of any complaints.

When replacing an entrance door in a condominium, coordinate the color and model with neighbors and the building manager. Some residential buildings have internal rules for the appearance of entrance doors.

How to prepare your home for installation?

  • Ensure free access to the door and remove furniture/items from the work area.
  • Cover the floor with plastic or old sheets – installation involves dust.
  • Check if electricity and lighting are available in the room.
  • Confirm with the professional the arrival time and necessary materials.

Common mistakes and how to avoid them

  • Choosing a professional without experience with the specific type of door
  • Unspecified conditions for dismantling/installation and transport
  • Lack of contract and warranty
  • Installation with cheap, uncertified fasteners

Door installation is an investment in comfort, security, and appearance. In 2025, digital platforms like Fix! allow you to choose among proven professionals, compare offers, and benefit from secure payment. This is the future of home services — easier, transparent, and secure for every client.
