Marvin Tilt Pac windows are a popular brand of double hung windows known for their quality and durability. However, as with any window, issues can arise over time that require maintenance or repair.
In this article, we’ll explore some of the most common Marvin Tilt Pac window problems homeowners face, along with troubleshooting tips and solutions to get your windows working like new again.
Problems With Marvin Tilt Pac windows
Here is a list of these issues:
- Difficulty Opening/Closing Sash
- Air/Water Leakage
- Condensation/Fogging Between Panes
- Hardware/Lock Issues
- Clouding/Hazing on Glass
- Wood Decay/Rot
- Glass Breakage
- Operational Noise
Let’s talk about them in detail.
Difficulty Opening/Closing Sash
One of the most frustrating problems with Marvin Tilt Pac windows is when the sash (the part that moves up and down) becomes difficult to operate. Several factors can cause this:
- Paint Buildup
Over time, layers of paint along the window jambs (side frames) can cause the sash to stick. Carefully scraping away paint buildup with a plastic putty knife can help. Avoid gouging into the wood.
- Off-Track Sash
If a sash is bumped hard, it can sometimes come out of the track along the jamb. This misalignment makes raising or lowering the sash difficult. Get the sash back in the track by tapping it gently with a rubber mallet.
- Worn Tilt Latches
Marvin Tilt Pac windows are designed to tilt in for easy cleaning. Special latches on the top of the bottom sash allow this tilting. When these latches become loose or worn out, it can cause the sash to drag. Replace worn latches to restore smooth operation.
- Broken Sash Cords/Chains
The sash on double hung windows is held in place by a system of cords or chains behind the jambs. If these components break, the sash can fall out of alignment and become difficult to operate. Sash cords need periodic replacement.
- Excessive Friction
Simple friction between the sash and jamb can make windows harder to open and close over time. Lubricating with wax candle or silicone spray can help reduce friction. Avoid oil-based lubricants which can damage paint or wood.
Air/Water Leakage
Another common problem with Marvin Tilt Pac windows is air and water leaks. This allows energy loss and risk of water damage. Several maintenance tips can help:
- Inspect/Replace Weatherstripping
The weatherstripping between the sash and jamb forms a seal against water/air infiltration. Over time this can wear out or get compressed. Replacing torn or missing weatherstripping will help.
- Check for Level/Plumb
If a window is not perfectly level or the jambs are out of plumb, gaps can form allowing air/water through. Shim the window or adjust the jambs to bring the unit back to level and plumb.
- Look for Gap Fillers
Small gaps can form where the inner and outer sash meet, allowing air/water through. Using gap filler rope or weatherseal tape in these spots helps seal things up.
- Caulk Exterior Trim
Cracks in the exterior trim around a window can lead to leakage. Carefully caulk along the exterior trim with a high-quality exterior caulk. Avoid caulking areas where water drainage holes exist.
Condensation/Fogging Between Panes
Seeing condensation or fogging between the glass panes is a sign of a broken seal in an insulated glass (IG) unit.
The air space between panes is meant to be airtight. Once this seal fails, replacement of the IG unit is required.
Marvin has robust warranties on IG units to cover replacements.
Hardware/Lock Issues
Marvin Tilt Pac windows feature high-quality hardware for tilting, locking, and opening sash. But issues like loose or damaged hardware can arise:
- Loose Hinges
The sash tilts in for cleaning on special hinges. If these come loose, tightening the hinge screws will help. Some disassembly may be needed first.
- Broken Tilt Latches
The latches activated by the tilt release buttons can break over time. Replace broken tilt latches so the sash can tilt properly for cleaning.
- Damaged Locks
Locks, keepers and lock strike plates are potential points of failure. Lubricating with graphite powder can help, but damaged components often need replacement.
- Bent Sash Lifts
The sash lifts attached to the bottom of the top sash allow you to pull it down. If these get bent they won’t work properly. Use pliers to straighten bent lifts.
Clouding/Hazing on Glass
Marvin windows use high-quality tempered and low-E glass designed to resist damage. But improper cleaning or environmental factors can lead to clouding, hazing, or etching on glass surfaces:
- Hard Water Spotting
Minerals in water used for cleaning can leave behind stubborn spots and residue. Use soft, filtered water and specially formulated glass cleaners.
- Seal Failure
In some cases, the perimeter seal between the glass and frame can fail, allowing air and moisture between the panes that clouds the glass. Requires professional reglazing or glass replacement.
- Etching from Salt Spray
Homes near the ocean can experience etching of exterior glass over time from sea salt in ocean spray. Requires glass replacement to correct. An annual coating can help prevent.
- Etching from Lawn Chemicals
Lawn fertilizers and chemicals can spray or splash on glass and permanently etch surfaces. Always clean immediately after applying lawn chemicals.
Wood Decay/Rot
Since Marvin Tilt Pac windows utilize natural wood frames and sash, maintaining proper paint and caulk is crucial to prevent decay over time. Watch for:
- Failing Paint/Stain
When the paint or stain finish starts seriously peeling and flaking, it allows moisture into the wood which can lead to decay. Refinish with fresh paint or stain promptly.
- Cracks/Gaps in Caulk
Any exterior gaps or cracks around frames should be well-caulked to prevent water ingress. Inspect annually and re-caulk as needed with a quality exterior caulk.
- Proper Overhangs
Adequate roof overhangs and protective trim/flashing helps minimize wood rot risks. Add kickout flashing if none exists. Expand overhangs if feasible.
- Condensation Buildup
Excess interior humidity can lead to condensation forming on windows, leading to wood rot over time. Maintain proper ventilation and dehumidification.
Glass Breakage
The tempered and laminated glass in Marvin Tilt Pac windows is very impact-resistant. But breakage can still occasionally occur due to:
- Direct Impact
A significant direct impact, such as a thrown object or person hitting the glass, can cause breakage. Always use screens to protect glass.
- Tense Glass Panels
When glass is excessively compressed in the frame, it creates tension that makes breakage more likely from temperature shifts or minor impacts.
- Nickel Sulfide Inclusions
A rare imperfection in glass manufacturing can cause spontaneous breakage later on after installation. Marvin fully warrants such manufacturing defects.
- Minor Frame Movement
Shifts in the window frame over time, even very slightly, can lead to stress points in the glass causing breakage. Ensure stable, adequately supported framing.
Operational Noise
Some minor noise when operating windows is normal, but excessive sliding, tapping, or banging sounds indicate potential problems:
- Loose Latches/Locks
Loose tilt latches or sash locks can vibrate or tap against the jamb while operating the window, creating noise. Tighten hardware screws or shim surrounding gaps.
- Voids in Weatherstripping
Gaps or voids in the weatherstrip can allow the sash to rattle within the jamb. Replace damaged weatherstripping.
- Debris in Channels
Buildup of dirt and debris in jamb channels can cause friction and rattling noises. Clean tracks with a vacuum and soft brush.
- Misaligned Sash
A sash that is not properly aligned may hit or rub against the jambs during operation. Have a professional realign the sash.
