Jets overhead can make a beautiful Point Loma day feel a little less peaceful. If you live in Loma Portal or Point Loma Heights, you know the sound of aircraft is part of daily life. You want a quieter home without wasting money on fixes that do not work. This guide gives you a clear, prioritized plan for smarter remodeling and pre‑listing upgrades that reduce noise and protect indoor air quality. Let’s dive in.
Why aircraft noise is different in Point Loma
San Diego International Airport sits close to the urban core, and approach paths have long crossed parts of Point Loma. Community feedback often cites aircraft noise as a top nuisance in these neighborhoods. Airport and federal planning commonly use Day‑Night Average Sound Level to assess exposure, with 65 dB DNL a typical residential compatibility threshold. You notice the peaks most during individual overflights, which is why your home needs to handle sudden, broadband events with low‑frequency energy.
Windows and doors are usually the weakest links for airborne sound. Low frequencies travel through light, leaky assemblies more easily, so the winning formula is mass, airtightness, and layered glazing. You can learn more about how airports plan for noise in FAA Part 150 materials and local community resources from the San Diego International Airport noise program.
STC, OITC, and what they mean to you
STC (Sound Transmission Class) rates how well a wall or window blocks airborne sound in a lab test. It focuses on mid‑frequencies, which means it is helpful but not the full story for aircraft noise. OITC looks more at lower frequencies and can be a useful companion number. In general, higher STC and OITC means quieter.
Installed performance is almost always lower than lab ratings due to flanking paths like gaps and penetrations. Many people perceive a real improvement when STC increases by about 5 to 10 points. To protect sleep, aim for meaningful installed gains in bedrooms, not just a bigger lab number on paper.
Your Point Loma quiet‑home plan: priorities
Start where you will feel it most. Combine measures for the best results.
A. Do now: low cost, low disruption
- Seal window and door perimeters, add quality weatherstripping and door sweeps.
- Swap in solid‑core bedroom doors with perimeter seals.
- Hang heavy, lined curtains in bedrooms that face the flight path.
- Add area rugs and soft furnishings to cut interior echo.
- Seal obvious penetrations: attic hatches, recessed lights, outlets, and chases.
B. Next step: moderate cost, strong impact
- Upgrade the noisiest room windows first. Use acoustic laminated glazing or add well‑spaced secondary glazing on bedrooms.
- Plan mechanical ventilation so you can keep windows closed and maintain fresh air. Select quiet ERV or HRV units and muffled duct runs.
- Replace leaky exterior and sliding doors with insulated frames and continuous seals.
- Add a second layer of drywall with a damping compound on the most exposed walls or in key rooms.
C. Major remodel: highest impact
- Replace full window and frame assemblies with tested acoustic units.
- Reconfigure layouts to move bedrooms to the quieter side and use closets or baths as buffers.
- Decouple walls or ceilings in priority rooms to reduce structure‑borne transmission.
- Install a full ducted ERV or HRV with acoustically treated intakes and silencers.
Windows and glazing that actually help
If your home still has older single‑pane windows, they are likely the main path for aircraft noise. Modern double‑pane units help. Adding laminated acoustic glass improves both high‑ and low‑frequency performance. Larger total glass thickness and bigger sealed airspaces generally improve isolation.
Frames and installation matter as much as the glass. Specify insulated vinyl, fiberglass, or thermally broken aluminum frames with deep rabbets and continuous compression gaskets. Insist on careful perimeter sealing to avoid flanking leaks. If replacement is costly or restricted, secondary glazing on the interior can deliver impressive low‑frequency gains and is a strong value for bedrooms.
What to ask for:
- Manufacturer test reports with STC and, if available, OITC for the whole unit.
- Details on installed performance expectations and references for similar homes.
- Acoustic perimeter seals and documented installation steps to control leakage.
Seal tight, then ventilate right
Better airtightness reduces both noise and energy waste. The tradeoff is fresh air. California’s energy code and national guidance call for mechanical ventilation in tighter homes. ASHRAE Standard 62.2 outlines minimum residential ventilation rates.
Practical steps:
- Add weatherstripping, door sweeps, and proper thresholds at exterior doors.
- Seal outlets, recessed lights, plumbing and HVAC penetrations, and attic access.
- Choose quiet bath and kitchen fans with low sone ratings and backdraft dampers.
- For whole‑home ventilation, select ERV or HRV units with variable speed control. Use lined ducts, acoustic silencers, and locate intakes on the quiet side with baffled paths.
In coastal San Diego, many residents keep windows closed for noise control. Plan ventilation upgrades at the same time as sealing to maintain healthy indoor air.
Layout and finishes that work harder
If you are already planning a remodel, you can gain a lot by rethinking the floor plan. Put bedrooms on the quieter side when possible. Where that is not an option, turn closets, baths, or hallways into buffer zones between the exterior wall and sleep spaces. Keep living and kitchen areas on the noisier side if that supports bedroom quiet.
Interior finishes also help with perceived loudness. Solid‑core interior bedroom doors with good seals reduce sound bleed. Thick rugs, upholstered pieces, and heavy draperies cut room reverberation, which softens the peaks you hear during overflights. Built‑ins on noisy walls add mass and an extra barrier.
For construction‑level upgrades, add another layer of drywall with a viscoelastic damping compound on exposed façades. In especially sensitive rooms, decouple walls or ceilings with resilient channels or double framing. Increase roof or ceiling mass and insulation if overhead flights are most noticeable, and keep the ceiling air barrier continuous.
Selling under the flight path: smart prep and proof
If you plan to list a home in Point Loma, focus on sleep and comfort. Prioritize bedrooms for window upgrades and sealing. Document what you changed and why. Buyers respond well to clear, verifiable improvements that match daily life needs.
Strong seller moves:
- Keep manufacturer test data for window and door upgrades.
- Log before‑and‑after sound levels or peak events with a simple meter or consultant.
- Share your ventilation plan to show how you protected indoor air quality.
- Confirm permit needs for window and door work with the City of San Diego.
- Discuss disclosure obligations with your real estate professional and legal counsel as needed.
These steps make your home feel calmer during showings and support value during negotiations. They also help buyers see that aircraft noise has been addressed thoughtfully and systematically.
Health and comfort context
Aircraft noise does not simply distract you. Sudden peaks can disrupt rest. Global health guidance highlights the value of lower indoor noise levels for well‑being and sleep quality. For broader context, see the World Health Organization’s Environmental Noise Guidelines. In your home, results come from combining better glazing, tight air sealing, and controlled ventilation.
Your Point Loma checklist
- Assess and document baseline noise at different times of day.

FAQs
What is STC, and how much improvement will I notice?
- STC rates how well a wall or window blocks airborne sound in a lab. Many people notice a meaningful difference when STC increases by about 5 to 10 points, though field performance is often lower than lab results.
Which windows work best under Point Loma flight paths?
- Units with laminated acoustic glass, deeper frames, large sealed airspaces, and continuous compression gaskets perform well. Quality installation and perimeter sealing are essential to avoid flanking leaks.
Is secondary glazing a good alternative to full window replacement?
- Yes. Adding an interior secondary pane creates two airspaces and often improves low‑frequency attenuation. It can deliver strong bedroom results when full replacement is costly or restricted.
Do I need mechanical ventilation after air‑sealing?
- If you tighten the home, plan for controlled fresh air. Standards such as ASHRAE 62.2 recommend minimum ventilation rates. ERV or HRV systems with quiet duct design let you keep windows closed while maintaining indoor air quality.
Are permits required for window or door work in San Diego?
- Window and door replacements often require permits, especially if openings are modified. Confirm requirements with the City of San Diego or a licensed contractor before starting work.
How can I show buyers that noise upgrades really work?
- Provide product test data, installation documentation, and before‑and‑after sound logging summaries. Clear, objective proof supports your listing narrative and buyer confidence.
