Short answer: Winter pre-construction termite treatment works well in Islamabad because the dry, settled soil of November to January soaks up the termiticide evenly, building activity is at its peak, and the barrier is in place months before the spring swarm season. Booking the three soil treatment stages while your foundation is open is the cheapest way to stop deemak from ever reaching the new house. Makhdoom Services has been Serving Since 1982, and our pre-construction termite treatment in Islamabad comes with a 10-Year Written Warranty (Pre-Construction).
Across DHA, Bahria Town, Gulberg Greens, Park View City, B-17 and G-13, the cool months are when most new plots are excavated and grey structures go up. This guide explains why winter is a strong season for anti-termite soil work, what the three stages involve, how to plan them with your contractor and what to send us before the first visit.
Why Winter Pre-Construction Termite Treatment Suits Islamabad
Subterranean termites live in the soil around the twin cities all year. In summer and during the monsoon they forage close to the surface, and from February to April mature colonies send out winged swarmers to start new nests. Winter is the quiet window before that cycle restarts, and it lines up neatly with the main construction season.
- Dry, firm soil absorbs the solution evenly. After the monsoon, trenches and fill dry out. A diluted termiticide spreads into dry soil in a uniform layer instead of running off or pooling, as it can on waterlogged ground.
- Fewer rain interruptions. October to December is usually the driest part of the year in Islamabad and Rawalpindi, so treated soil can be covered on schedule.
- The barrier is ready before swarm season. A house whose foundation, plinth and floor base are treated in winter already has a continuous chemical layer beneath it when spring swarmers look for new sites.
- Contractors are on site anyway. Most builders pour foundations in the cool months, so termite visits fit into work that is already happening.
None of this means summer work fails. It means winter pre-construction termite treatment removes several of the variables that can weaken a soil barrier, which is why many builders we work with plan it this way.
What the 3-Stage Termisol 25 EC Soil Barrier Involves
A soil barrier only works if it is continuous. Treating the foundation alone leaves the plinth fill and floor base open, and termites simply travel around the treated band. That is why we lay the barrier in three visits, each using Termisol 25 EC diluted with water on site and applied with pressure sprayers.
Stage 1: Foundation (open excavation)
Once excavation is complete, the trench beds, trench side walls and column pits are drenched before any concrete or brick foundation goes in. This puts the first treated layer directly beneath the load-bearing walls.
Stage 2: Plinth (backfill)
As the plinth is filled, each layer of earth is wetted with the solution while it is spread, and the inner face of the plinth walls is coated. Treating layer by layer stops untreated pockets from forming inside the fill.
Stage 3: Flooring (under the floor base)
After compaction, a continuous film is sprayed over the whole covered area, including porch, garage and servant quarter, just before the floor base is laid. Service and conduit entry points receive extra solution because they are common termite routes.

Planning Winter Pre-Construction Termite Treatment With Your Site Engineer
Timing is what makes winter pre-construction termite treatment work. Each stage has to happen after the soil is exposed and before it is covered, so the visits follow your construction schedule rather than a fixed calendar.
- Message us about three days before the foundation pour so the crew can reach the site while trenches are still open.
- Allow the solution to soak in before concrete or fill is placed. Our crew agrees a short gap with your site engineer.
- Call again before plinth filling and before the floor base, so Stages 2 and 3 are not skipped in the rush to finish.
- Keep wood offcuts, shuttering and old roots out of the fill. Buried timber feeds colonies and weakens protection.
- Treat later additions too. Lawn beds, ramps and boundary fill added after the main build can bridge untreated soil to the plinth.
Overseas owners building in DHA or Bahria Town can follow each stage through photos and short videos shared on WhatsApp after every visit. Each visit is logged with its date and covered area for the warranty file.
Society-by-Society Notes for New Builds
Ground conditions vary across the capital. In DHA Islamabad and Bahria Town Islamabad, large plots are often cut into former scrub and farmland where old roots support established colonies. Gulberg Greens and Park View City sit near green belts that keep soil moisture higher, while B-17 and G-13 have many 5 to 10 marla houses going up side by side, and neighbouring excavations disturb colonies that then look for new food. In each case the answer is the same: book winter pre-construction termite treatment while your soil is open.
If your house is already finished, soil treatment from above is no longer possible. Our termite control Islamabad service and termite control Rawalpindi service use drill-and-inject treatment for existing buildings instead.
Common Winter Pre-Construction Termite Treatment Mistakes
Most failures we are called to inspect come from planning gaps, not the product. Watch for these when you schedule winter pre-construction termite treatment:
- Treating on frozen or water-logged mornings. After a winter rain, let standing water clear from the trench surface before application. Winter pre-construction termite treatment on standing water dilutes the mix unevenly.
- Rushing the pour. Short winter days push crews to cover soil quickly. Agree the soak time in advance so the barrier is not disturbed.
- Forgetting the boundary wall and septic area. These are often dug separately and left out of the plan, yet they sit close to the main structure.
- Assuming cold weather means no termites. Colonies stay active below the frost-free layer, so winter pre-construction termite treatment is protection for the coming season, not a wasted visit.
- Losing the visit record. Keep the dated photos and stage notes; they form part of your 10-Year Written Warranty (Pre-Construction) file.
Getting these details right is what turns winter pre-construction termite treatment from a one-time spray into long-term protection for the family that moves in.

Warranty: Pre-Construction vs Post-Construction
- 10-Year Written Warranty (Pre-Construction): issued when all three soil stages are completed by our crew.
- 5-Year Written Warranty (Post-Construction): issued for drill-inject treatment of an occupied or finished building.
Under both, if termites appear in a treated area during the warranty period, we re-treat the affected area free of charge. The warranty is shared on WhatsApp and as a signed paper copy.
How the Cost of Winter Pre-Construction Termite Treatment Is Worked Out
We do not publish a rate list, because two plots of the same size can need very different amounts of work. The quote depends on:
- Plot size and covered area, including basement, porch and annexes.
- Construction stage: a site with all three stages open is planned differently from one where only the floor base remains.
- Soil and wood condition: old roots, buried timber or high moisture change the dosage.
- Dosage: the litres of Termisol 25 EC mix required for the covered area.
Send your plot size, drawings or site photos on WhatsApp 03004188502 for a free estimate. If a site visit is needed, the Rs 2,000 visit charge is refunded/adjusted in your final bill when you book the job with us. Builders who prefer to buy the product can find Termisol 25 EC (Rs 9,000 per litre) on our product page, but correct dosage and full coverage at every stage are what decide how long the barrier lasts.
What to Send Before the First Visit
- Plot size in marla or kanal and the covered area per floor
- Whether there is a basement
- The current stage of work and expected pour dates
- The contractor or site engineer’s phone number
- Photos of the open trenches or plinth, or a simple ground-floor plan
With these details we plan your winter pre-construction termite treatment, confirm the visit dates and the mix required for each stage, and share a written estimate.
Winter Pre-Construction Termite Treatment: FAQs
Is winter a good time for pre-construction termite treatment in Islamabad?
Yes. From October to January the soil is usually dry and firm, rain interruptions are fewer and construction activity is high, so the three soil stages can be applied evenly and covered on schedule, well before the February to April swarm season.
Do termites stop being active in winter?
No. Subterranean colonies stay active deeper in the soil during cold months and return to the surface as temperatures rise. Treating the soil in winter means the barrier is already in place when activity increases in spring.
Can I treat only the foundation to save time?
A single foundation treatment leaves the plinth fill and floor base untreated, and termites can travel around the treated band. The 10-Year Written Warranty (Pre-Construction) applies when all three stages are completed.
Which product do you use?
We use Termisol 25 EC, a fipronil concentrate diluted with water on site and applied by pressure sprayer at each stage.
My house is already built. What are my options?
Finished buildings are treated with drill-and-inject work along floor-wall joints and entry points, which carries a 5-Year Written Warranty (Post-Construction).
