Ault’s housing is old enough that lead-based paint is a real concern. As a grain-elevator and railroad town founded in the early twentieth century on the northern Weld County plains, much of Ault’s stock predates 1978, the year the federal government banned lead in residential paint. In homes from that era, lead can lurk under newer coats of paint on windows, doors, trim, and siding, and it becomes a hazard when old paint chips, peels, or turns to dust. Lead is especially dangerous to young children and pregnant women, where even low exposure is linked to developmental harm. This page explains how lead testing ault families should approach the issue, where lead hides, and what testing costs. This summary reflects EPA, HUD, and CDC guidance current as of 2026; consult a certified professional for testing decisions.

Lead testing in Ault: what to know

Lead testing determines whether the paint and dust in an older home contain lead at hazardous levels. Because Ault’s housing leans toward the pre-1978 era, the safe assumption before any renovation or before young children move in is that lead-based paint may be present until testing shows otherwise. For the broader background on this hazard, our guide to asbestos and lead in pre-1978 housing explains why the 1978 cutoff is the key dividing line.

There are two main approaches. A certified inspector can use an XRF analyzer, a handheld device that reads the lead content of painted surfaces without damaging them, or collect paint chip and dust-wipe samples for laboratory analysis. Dust-wipe sampling is particularly important because lead-contaminated dust, not just visible paint, is the most common route of childhood exposure. The right method depends on whether you need a full inspection, a risk assessment, or clearance after work.

The hazard is dust and chips, not intact paint. Lead paint sealed under sound newer coats and left undisturbed poses limited risk. The danger comes from friction surfaces, such as windows that rub each layer to powder, and from sanding or scraping during a renovation. That is why testing matters most before a remodel and in homes where small children live.

Knowing where the lead is changes how a family lives in an older home, often in small, practical ways. A household that learns its window sills and a back porch rail are the lead-bearing surfaces can keep those areas clean, repaint and maintain them, and keep young children’s play away from bare soil at the drip line, all without a major renovation. Testing turns a vague unease about an old Ault house into a short, specific list of surfaces to watch and manage.

Why Ault homes need lead testing

The age of the housing is the driver. Ault’s older cottages and farmhouses, many dating to the grain-elevator era, were painted with lead-based products as a matter of course before 1978. Decades of repainting may hide that original lead under newer layers, but the lead is still there, and any disturbance that reaches the old coats can release it.

The plains climate accelerates the problem. Harsh sun, wind-driven grit, and the freeze-thaw cycle of cold plains winters weather exterior paint hard, so siding, porch posts, and window trim on older Ault homes chip and flake over time. Those chips fall into the soil around the foundation, where children play, creating a contamination path that is easy to overlook. Interior friction points, especially old double-hung windows, grind paint into dust with everyday use.

Older farm homes that have been repainted many times are deceptive. A fresh coat looks safe, but it only covers the lead beneath rather than removing it. A family moving young children into a century-old Ault house, or planning to sand and repaint it, should test first, because the visible condition of the paint says nothing about what lies underneath.

What an Ault lead test covers

A professional lead evaluation can take the form of a paint inspection, which identifies lead on surfaces throughout the home, or a risk assessment, which focuses on where lead is actively creating a hazard through deteriorating paint, dust, or contaminated soil. Many older-home situations call for both, since knowing where the lead is and where it is dangerous are different questions.

XRF testing and lab samples

An XRF analyzer reads lead content directly through the paint layers without cutting into the surface, making it efficient for surveying many painted components quickly. Where confirmation is needed, paint chip samples go to an accredited lab. Dust-wipe samples taken from floors, window sills, and window wells are analyzed for lead loading and are the best measure of the dust hazard a child would actually contact.

Soil and exterior testing

Because exterior paint on older Ault homes weathers and sheds chips into the surrounding soil, a thorough assessment can include soil samples from the drip line and play areas. Lead in soil is a frequently missed exposure route, especially in a town where children play in yards around old houses, so an assessment that checks the ground as well as the paint gives a more complete picture.

Lead testing cost in Ault

A professional lead inspection or risk assessment in the Greeley and Weld County market typically runs about $250 to $500 for a single-family home, depending on size and the number of components evaluated. Individual lab analysis of paint chip or dust-wipe samples runs roughly $20 to $50 each. A combined inspection and risk assessment, with XRF readings plus dust-wipe and soil samples, costs more but gives the fullest picture of an older home.

The cost is small against the stakes. Childhood lead exposure is linked to lasting developmental and learning harm, and there is no safe blood-lead level. For a family with young children moving into or renovating a pre-1978 Ault home, a few hundred dollars of testing identifies exactly which surfaces need safe-work practices and which are sound, so remediation effort and money go where they matter.

For buyers, folding lead testing into the broader due-diligence picture is efficient. Ault homes within the county share a similar pre-1978 profile, documented in our Weld County lead testing hub, and pairing a lead assessment with an asbestos survey of the same vintage home covers both pre-1978 hazards in one coordinated visit.

Colorado regulations and disclosure

Federal law requires sellers and landlords of pre-1978 housing to disclose known lead-based paint and provide the EPA’s lead hazard pamphlet to buyers and tenants. Renovation, repair, and painting work that disturbs lead paint in pre-1978 homes must follow the EPA’s RRP Rule, meaning the contractor should be RRP-certified and use lead-safe work practices that contain dust and clean up thoroughly. For Ault homeowners, the practical point is that sanding or scraping old paint in a pre-1978 home is regulated work, not a casual weekend project.

Colorado’s Seller’s Property Disclosure also asks about known environmental hazards. A documented lead assessment protects a seller by establishing what was known and lets a buyer plan a renovation safely. For nearby comparison, our lead testing in Eaton page covers the same pre-1978 concerns in an adjacent town.

Neighborhoods and areas served

Lead concerns concentrate in Ault’s older housing: the cottages near the historic grain-elevator core and original townsite, and the early-twentieth-century farmhouses on surrounding acreage. These are the homes most likely to carry lead paint under newer coats and to have weathered exterior paint shedding into the soil. Newer infill homes built after 1978 are essentially free of the concern. Service typically extends to adjacent Eaton, Pierce, Nunn, and nearby Greeley.

Because the build year of the specific house, not the part of town, determines lead risk, the deciding factor is always the construction era. A century-old farmhouse and a 1960s in-town cottage both predate the ban and warrant testing, while a recent build generally does not. That is why an assessment focuses on the age and condition of the painted surfaces rather than the address.

What to do when lead is found

A positive lead result in an Ault home is common given the age of the stock, and it does not mean the house is uninhabitable. It means specific surfaces need management. Where paint is intact and not on a friction surface, the safest approach is often to leave it undisturbed and maintain it, keeping it painted over and watching for any chipping. Lead paint that is sound and not being abraded poses far less risk than the same paint left to peel, so good maintenance is itself a form of hazard control.

Friction and impact surfaces are the priority for action. Old double-hung windows that grind paint to dust every time they open, doors that rub their frames, and stair treads and railings that take wear are the components most likely to generate lead dust a child can ingest. Addressing these, sometimes by replacing the window or repairing the surface, often does more to reduce exposure than tackling broad wall areas that are not being disturbed. A risk assessment ranks the surfaces so a family knows where to start.

Any work that disturbs lead paint should follow lead-safe practices. In a pre-1978 home, that means containing the dust, using wet methods rather than dry sanding, cleaning thoroughly with HEPA equipment, and verifying the area afterward. For larger jobs, an RRP-certified contractor is the right choice, since they are trained and equipped to do this without spreading contamination. A homeowner who scrapes old window paint dry on a breezy Ault afternoon can create exactly the dust hazard the testing was meant to prevent.

For families with young children, interim controls plus regular cleaning go a long way while larger fixes are planned. Wet-wiping sills and floors, keeping children’s hands and toys clean, and addressing bare soil around the foundation reduce the day-to-day exposure that matters most. Pairing those habits with a documented assessment gives an Ault family a clear, prioritized path rather than a vague worry about an old house.

How to choose an Ault lead testing provider

Use a certified lead inspector or risk assessor who can perform XRF testing, collect lab samples, and explain the difference between a paint inspection and a risk assessment so you get the right service for your situation. A credible provider gives you a written report identifying lead surfaces, dust hazards, and recommended controls, along with guidance on whether RRP-certified contractors are needed for your planned work.

For a family with young children, prioritize a provider who includes dust-wipe sampling and, for an older home with weathered exterior paint, soil testing around the foundation and play areas. Those two measures capture the exposure routes children actually contact, which a paint-only inspection can miss. Ask specifically that windows and friction surfaces be evaluated, since they are the most common dust generators.

Confirm the provider keeps testing independent of any remediation sale, so the assessment is an honest measurement rather than a pitch. Pairing the lead assessment with an asbestos survey of the same vintage home is efficient and covers both pre-1978 hazards in a single coordinated visit, which is usually the best value for an older Ault property.
