Proper window maintenance isn't just about keeping your windows clean—it's about protecting your investment, ensuring energy efficiency, and maintaining your home's curb appeal. With over 15 years of experience in window installation and maintenance, we've developed this comprehensive schedule that homeowners can follow to keep their windows in optimal condition throughout the year.

Monthly Window Maintenance Tasks

Regular monthly maintenance prevents small issues from becoming costly repairs. Here's what you should do every month:

Visual Inspection (15 minutes)

  • Check for cracks in glass or frame
  • Look for gaps in weatherstripping
  • Inspect for water damage or moisture buildup
  • Test window operation (opening/closing)

Basic Cleaning (30 minutes)

  • Clean window tracks and sills
  • Wipe down frames with appropriate cleaner
  • Remove debris from drainage holes
  • Check and clean window screens

Hardware Check (10 minutes)

  • Test locks and handles
  • Check for loose screws or hardware
  • Ensure smooth operation of moving parts
  • Listen for unusual sounds during operation

Professional Tips

  • Set a monthly reminder on your phone for the first Saturday of each month
  • Keep a maintenance log to track issues and improvements
  • Take photos of any problems for professional consultation

Seasonal Window Maintenance Guide

Each season brings unique challenges for your windows. Here's how to prepare:

Spring Preparation (March-May)

  • Deep clean windows inside and out
  • Replace weatherstripping if damaged
  • Lubricate hinges and moving parts
  • Check and repair caulking
  • Inspect for winter damage

Summer Maintenance (June-August)

  • Focus on UV protection and ventilation
  • Clean and inspect window screens
  • Check air conditioning window units
  • Monitor for expansion-related issues
  • Ensure proper drainage during storms

Fall Preparation (September-November)

  • Prepare windows for winter weather
  • Install storm windows if applicable
  • Check insulation and energy efficiency
  • Clean gutters near windows
  • Trim vegetation away from windows

Winter Care (December-February)

  • Monitor for condensation issues
  • Check for ice dam formation
  • Maintain proper indoor humidity
  • Avoid using harsh de-icing chemicals near windows
  • Keep windows clear of snow buildup

Professional Insight

Frequently Asked Questions

Everything you need to know about our window and door repair services

Yes, the initial inspection and our technician's visit to assess the work are completely free. No hidden fees and no obligations. If you decide to go ahead, the technician will prepare a clear quote on the spot, explain everything to you and, if you agree, can usually do the work right away during the same visit.

Of course. We provide a warranty both for the work carried out and for the materials used, in line with the laws of the Republic of Lithuania.

The price depends on the type of window, the issue, and the materials needed. When the technician arrives, they give you an exact quote on site with no hidden charges, and you decide yourself whether you want to proceed with the repair.

Yes, our window service operates all over Lithuania: in Vilnius, Kaunas, Klaipėda, Panevėžys, Šiauliai and other cities and towns.

Booking a free visit is very simple. Just give us a call or fill in the online booking form – in both cases it only takes a few minutes.

In most cases repair is enough: replacing seals or mechanisms, improving insulation, adjusting the fittings, cleaning and lubricating the hardware. This is usually much cheaper than installing brand new windows.

Repair is cheaper, because you don't have to buy new windows, remove the old ones, dispose of them or redo the interior finishes afterwards. Repair saves both time and money and is significantly more cost‑effective.

We work with all major brands: Rehau, Veka, KBE, Schüco, Salamander, Aluplast and many others. Our technicians are trained to work with the specific mechanisms used by each manufacturer.

Yes, you can pay by all major bank cards, by bank transfer or in cash. Payment is made after the work is completed.
