Your Windows Are Leaking Money. We Seal Them Shut.
Professional window sealing and draught proofing across Riga, Jūrmala, and surrounding areas. We replace perished gaskets, restore compression seals, and eliminate cold air infiltration — cutting your heating bills and restoring comfort in every room.
The Hidden Crisis Behind Your Window Frames
You touch the glass and it is warm. You check the frame and it looks intact. Yet every winter evening, a cold ribbon of air finds your ankles. Your radiators run constantly. Your energy bills climb. And you tell yourself this is just how Latvian winters feel.
It is not. That cold air is not coming through the glass. It is coming through failed window seals — the rubber and brush components that create the airtight barrier between your frame and sash. These seals compress thousands of times per year. They endure Riga’s freeze-thaw cycles, UV degradation, and the slow hardening that turns flexible rubber into cracked plastic. When they fail, your heated air escapes and outside air invades. Your windows are not broken. Their seals are.
Window sealing and draught proofing is the most overlooked home improvement in Latvia. It costs a fraction of replacement. It delivers immediate, measurable results. And it is the service MaxiLux has refined into a science.
What Happens When You Ignore a Broken Window Seal
The consequences start small and compound relentlessly. Here is what a failed seal costs you — financially, physically, and structurally.
Your Heating Bills Spiral
A single failed window seal can increase heat loss by 15–25%. In a typical Riga apartment with six to eight windows, multiple failed seals mean your heating system works overtime to compensate. Latvian gas and electricity prices have risen sharply since 2022. Every cubic metre of heated air that escapes through a cracked gasket is air you paid to warm. Over a heating season, failed seals can add €200–€500 to a household's energy costs. Over five years, that is €1,000–€2,500 in preventable expense.
Your Home Becomes Permanently Uncomfortable
Draughts create cold spots. Cold spots create condensation. Condensation creates mould. You find yourself avoiding certain chairs, certain corners, certain rooms. You layer blankets in rooms where the thermostat reads 22°C because the air near the window is 14°C. Your children sleep in hoodies. Your guests comment on the chill. This is not normal. This is a solvable mechanical failure.
Your Window Frames Deteriorate
When outside air and moisture penetrate failed seals, they reach the internal frame structure. Wooden frames swell, rot, and warp. Aluminium frames corrode at joints. UPVC frames develop internal condensation that breeds mould and degrades reinforcement. What began as a €40 seal replacement becomes a €400 frame repair or a €1,200 full window replacement. Seal failure is the gateway to structural damage.
Your Double-Glazing Units Fail Prematurely
Failed seals allow moisture to reach the edge of your double-glazing unit. Over time, this breaches the primary seal of the glass unit itself. You notice misting between the panes. The unit's thermal performance collapses. Now you need sealed unit replacement — typically €120–€180 per unit — on top of the seal replacement you delayed. Addressing the frame seal early preserves the glass unit.
Your Health Suffers
Cold draughts suppress immune function. Condensation from failed seals creates black mould — Stachybotrys chartarum and Aspergillus species — which release mycotoxins linked to respiratory illness, chronic fatigue, and allergic reactions. In Latvia's damp climate, mould colonises within 24–48 hours of condensation forming. Children, the elderly, and immunocompromised individuals are most at risk. Window sealing is a health intervention, not just a comfort upgrade.
Your Property Value Declines
When prospective buyers or tenants inspect a property, they touch windows. They feel draughts. They see condensation stains and mould patches. They detect the musty smell of hidden moisture damage. Failed window seals signal deferred maintenance and hidden costs. A professionally sealed and draught-proofed home presents as cared-for, efficient, and move-in ready.
How Window Seals Fail — The Science Riga Homeowners Need to Know
Latvian window seals face a uniquely hostile environment. Understanding why they fail helps you recognise the warning signs before damage escalates.
Thermal Cycling
Riga's temperature swings from -25°C in January to +30°C in July. Seals expand and contract repeatedly. Each cycle micro-stresses the rubber polymer. After seven to ten years, the molecular structure breaks down. The seal loses elasticity and no longer rebounds when compressed.
UV Degradation
Sunlight attacks the carbon bonds in rubber seals. South-facing windows in Riga receive intense summer UV that accelerates this process. Seals on south-facing windows often fail three to five years earlier than north-facing equivalents. UV damage appears as surface cracking, colour fading, and a powdery residue when touched.
Compression Set
A seal compressed under a closed sash for years gradually loses its ability to spring back. When you open the window, the seal stays flattened. When you close it, the seal no longer fills the gap. This is called compression set, and it is irreversible without replacement.
Chemical Breakdown from Cleaning Products
Ammonia-based window cleaners and solvent wipes degrade rubber compounds. Homeowners inadvertently accelerate seal failure by using the wrong cleaning chemistry. We advise every client on seal-safe maintenance after installation.
Mechanical Damage
Forced closing, impact from cleaning tools, and pet scratching can tear or dislodge seals. Once the seal's continuous profile is broken, air and water bypass the barrier at the damage point.
The Results You Can Expect
Immediate Temperature Improvement
Most clients report a 3–5°C increase in temperature near sealed windows within 24 hours. The cold spot disappears. The room feels uniformly warm.
Heating Cost Reduction
Independent studies and our client feedback indicate 15–30% heating cost reduction after comprehensive draught proofing. In a typical Riga apartment, this pays back the service cost in one to two heating seasons.
Condensation Elimination
When warm interior air stops meeting cold exterior air at the seal line, surface condensation vanishes. Mould risk drops to near zero. You stop wiping windowsills each morning.
Noise Reduction
Quality compression seals add an acoustic barrier. Road noise, tram rumble, and neighbour activity decrease measurably. Clients in central Riga and near major roads report the most dramatic improvement.
Window Longevity
Properly sealed windows last years longer. The frame structure stays dry. The hardware operates smoothly. The glass unit retains its seal. Your windows become a long-term asset instead of a depreciating liability.
Who Needs Window Sealing & Draught Proofing
Homeowners in Pre-2010 Properties
If your windows have not been resealed in a decade, they are leaking. This is not speculation. Rubber seals have a finite lifespan, and Riga's climate accelerates ageing. Proactive sealing prevents the cascade of damage that follows seal failure.
Expats and Foreign Property Owners
You purchased a Riga property and discovered the heating costs are double what you expected. The windows look fine but the bills tell a different story. We diagnose, explain in English or Russian, and solve the problem without upselling unnecessary replacements.
Landlords and Property Managers
Draught-proofed properties rent faster, retain tenants longer, and generate fewer maintenance complaints. We offer multi-unit scheduling, bulk pricing, and documentation for tax deduction purposes.
Apartment Associations
When multiple units in a building share seal failure, the cumulative energy waste is enormous. We coordinate group sealing projects, standardise seal specifications, and deliver consistent results across the building envelope.
Owners of Soviet-Era and 1990s Housing
These properties often have original seals that hardened years ago. The frames are structurally sound but thermally useless. Our draught proofing service restores performance without the capital expense of full window replacement.
- Why Us
Why MaxiLux Is the Best Window Sealing & Draught Proofing Provider in Riga
We Diagnose Before We Treat
Most competitors sell seal replacement by the metre without understanding why your specific windows leak. We use thermal imaging and smoke testing to locate every infiltration path. We fix the root cause, not just the obvious symptom.
We Match Seals to Systems
Riga's window stock is heterogeneous. A seal that fits Rehau profiles fails in KBE grooves. We carry over forty seal profiles and source discontinued specifications for Soviet-era systems. Generic one-size-fits-all seals create new leaks. We install the seal your window was designed to use.
We Understand Latvian Climate Engineering
Seals rated for Mediterranean climates fail in Riga's -25°C winters. We specify cold-climate EPDM and TPE compounds with glass transition temperatures below -40°C. Our seals stay flexible when competitors' products turn rigid and crack.
We Adjust Hardware, Not Just Seals
A new seal is thicker than the old one. Without hinge and lock adjustment, the sash cannot compress the seal properly. We calibrate every mechanism to achieve optimal closure force. Your windows seal tightly and operate smoothly.
We Guarantee Our Work
Every draught proofing project carries a two-year workmanship guarantee and a five-year seal material warranty. If a seal fails prematurely, we replace it without charge. We also offer a free six-month inspection to catch any bedding issues early.
We Integrate with Window Repair
Because we are also Riga's leading window repair specialists, we identify frame damage, hardware failure, and glass unit degradation during our sealing assessment. If your windows need additional work, we coordinate everything in one visit. No multiple contractors. No conflicting schedules.
We Respect Your Property
Our technicians wear shoe covers, use dust sheets, and clean every work area. We work quietly and efficiently. For home offices and households with children, we minimise disruption and schedule around your needs.
We Speak Three Languages
Latvian, Russian, and English. No matter your background or comfort level, we communicate clearly and document thoroughly.
We Price Transparently
Our quotes are itemised and fixed. We charge per window based on size, system type, and seal specification — not vague hourly rates that inflate. You know the exact cost before we begin.

What Our Sealing Clients Say
"Our 1998-built flat in Purvciems was freezing despite new radiators. MaxiLux found every failed seal with a thermal camera, replaced them all in one day, and adjusted the hinges. The difference was immediate — we turned the thermostat down two degrees that same evening. Our January heating bill dropped 28%."

Frequently Asked Questions
Touch the seal. If it feels hard, cracked, or leaves a black residue on your finger, it has degraded. Hold a lit candle or smoke stick near the closed window on a windy day — flickering indicates air infiltration. Condensation between the glass panes or along the frame edge is another clear sign.
Yes. We seal UPVC, aluminium, timber, and steel windows. We work with casement, tilt-and-turn, sliding sash, and fixed-light systems. Even historic wooden windows in Vecrīga can be draught proofed with brush seals and compression gaskets that preserve their character.
A single window takes 30–45 minutes. A typical three-bedroom apartment with eight windows takes one day. We work efficiently and leave your home operational each evening.
It eliminates condensation caused by cold air infiltration at the seal. If condensation persists, it may indicate glass unit failure, inadequate ventilation, or structural damp — all issues we can diagnose and address.
Our EPDM and TPE seals are rated for fifteen to twenty years in Baltic climate conditions. We provide a five-year material warranty and a two-year installation guarantee.
Absolutely. We assess the full window condition during our survey. If hardware needs replacement or glass units have failed, we quote the complete solution and coordinate all work in one visit.
Yes. It reduces tenant complaints, lowers heating disputes, extends window lifespan, and improves rental appeal. Many landlords recover the cost through reduced vacancy and higher rental yields.
