Professional window sealing application for winter protection

Winter weather can be particularly harsh on windows, causing everything from condensation problems to ice damage and thermal stress. In Lithuania's continental climate, where temperatures can drop well below freezing for extended periods, proper winter window care isn't just about maintenance—it's about protecting your investment and ensuring your home remains comfortable and energy-efficient throughout the cold season.

Pre-Winter Window Preparation

Essential Fall Preparations (September-November)

Weatherstripping Inspection and Replacement

  • Check all weatherstripping for cracks, gaps, or deterioration
  • Replace damaged sections before first freeze
  • Use appropriate materials for your climate zone
  • Test seal effectiveness with smoke pencil or incense

Caulking and Sealing

  • Inspect exterior caulking around window frames
  • Remove old, cracked caulk and apply fresh sealant
  • Use cold-weather rated caulk for lasting protection
  • Pay special attention to corners and joints

Hardware Lubrication

  • Apply cold-weather lubricant to all moving parts
  • Use silicone-based products that won't freeze
  • Test all locks and mechanisms before cold weather
  • Ensure smooth operation throughout temperature range

Glass and Frame Cleaning

  • Deep clean all surfaces before winter
  • Remove dirt and debris that can cause ice buildup
  • Apply protective coatings if recommended
  • Clear drainage channels and weep holes

Professional Tips

  • Complete preparations before first hard freeze
  • Keep spare weatherstripping for emergency repairs
  • Document any issues for spring follow-up

Cold Weather Protection Strategies

Temperature Management

Indoor Climate Control

  • Maintain consistent indoor temperature (18-22°C)
  • Use proper humidity levels (30-50% relative humidity)
  • Avoid extreme temperature fluctuations
  • Ensure adequate air circulation around windows

Condensation Prevention

  • Monitor for condensation buildup
  • Improve ventilation in high-moisture areas
  • Use dehumidifiers if necessary
  • Address condensation immediately to prevent ice formation

Ice Prevention Measures

  • Keep windows clear of snow accumulation
  • Ensure proper drainage away from window wells
  • Never use salt or harsh chemicals on window surfaces
  • Install storm windows for additional protection

Emergency Protection

  • Keep emergency supplies (plastic sheeting, tape)
  • Know how to temporarily seal damaged windows
  • Have professional contact information readily available
  • Understand when to call for emergency service

Professional Insight

Professional tip: Never attempt to force open a frozen window. Allow natural thawing or use gentle warming techniques to prevent damage.

Winter Maintenance Routine

Daily Monitoring

  • Check for condensation or ice buildup
  • Ensure windows open and close properly
  • Monitor for drafts or air leaks
  • Clear snow from window wells and sills

Weekly Inspections

  • Test window operation in cold weather
  • Check weatherstripping condition
  • Inspect for any new cracks or damage
  • Clean interior surfaces as needed

Monthly Deep Checks

  • Examine exterior caulking and seals
  • Test all locking mechanisms
  • Check for ice dam formation
  • Assess overall window performance

Storm Response Protocol

  • Secure windows before severe weather
  • Check for damage after storms
  • Clear ice and snow safely
  • Document any issues for repair

Key Benefits

  • Prevents costly winter damage
  • Maintains energy efficiency
  • Ensures emergency egress capability
  • Extends window lifespan

Common Winter Window Problems

Ice and Frost Issues

Symptoms and Solutions

  • Ice on glass: Usually indicates humidity problems or poor insulation
  • Frozen mechanisms: Apply gentle heat, never force operation
  • Ice dams: Address roof and gutter issues, improve insulation
  • Frost patterns: May indicate air leaks or thermal bridging

Condensation Problems

  • Between panes: Indicates seal failure, requires professional repair
  • Interior condensation: Improve ventilation and humidity control
  • Exterior condensation: Normal in certain conditions, monitor for excess

Operational Issues

  • Sticking windows: Often due to swelling or ice formation
  • Draft problems: Check weatherstripping and caulking
  • Locking difficulties: Lubricate mechanisms with cold-weather products
  • Thermal stress cracks: Require immediate professional attention

Important Warning

Never use hot water or direct heat sources to remove ice from windows. Thermal shock can cause glass to crack or shatter.

Maximizing Energy Efficiency in Winter

Insulation Strategies

  • Use thermal curtains or cellular shades
  • Apply window film for additional insulation
  • Install storm windows for extra protection
  • Seal any air leaks immediately

Heat Retention Techniques

  • Close curtains at night for insulation
  • Open them during sunny days for solar gain
  • Use window treatments strategically
  • Maintain proper indoor humidity levels

Cost-Saving Measures

  • Regular maintenance prevents energy loss
  • Proper sealing reduces heating costs
  • Strategic use of natural light reduces artificial lighting needs
  • Preventive care avoids expensive emergency repairs

Professional Optimization

  • Annual energy audits
  • Thermal imaging assessments
  • Professional weatherization services
  • Upgrade recommendations for older windows

Key Benefits

  • Reduces heating costs by up to 25%

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.

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.
